In an earlier video I tested the world's smallest show laser, the LaserCube from Wicked Lasers. This time I will open it up to see what's inside it. I will also compare the inner workings with a similarly spec'ed show laser to see how they managed to make it this small and even find room for a battery too.

I will again give the standard warning: Do not look directly into laser beam with remaining eye.
Although if you needed that warning the last time I gave it, you may not be capable of reading it this time.
Note, Lasers also give off infrared and also not seen higher waves of light, these bouncs of walls and will eventually be the cause of migrane headaches. The beam is not all it gives out as a dot, but sprays other none seen at other angles not confined within the beam dot, So even not looking at the dot dorectly, refracted and reflected waves of the walls can give you over time health issues. With CD and DVD lasers it is no less than 40cm away from any part of you body, Bluray 80cm for example. So always wear the protective wavelength (for your laser bandwidth freqency) filter glasses. Lasers also give out other side band waves and if known what these are for you laser the the laser can be used for disrupting jamming someones radio tv sat reception or earvsdropping on their conversations or sending them sound.
The less expensive one really needs to have the scanners tuned. That's what all the trim pots are on the amplifier board are for. You'll have to display an ILDA test image for proper tuning. Things aren't being drawn correctly.
A pair of accurate Cambridge scanners would cost what the whole of this cube costs though, so you get's what you pay for, all in all great for the price
@@chrissinfinity8479 more actually double that cost and would not fit but i have scanners im working on fitting inside that will do true 38k
I am a very untechnical person, but I find these videos fascinating. short enough to watch in a coffee break or two but really informative. keep up the good work Brainiac75

Always cool to see a teardown, and this one doesn't disappoint! Fascinating piece of tech.
Glad you like it!

I'm working on getting together parts for a super small show laser. I am using a pico projector laser light engine and working on methods of beam steering. I don't know how small I can get it yet though.
For anyone else who wants to know what's inside lasers my channel has a bunch about them. I am a show laser technician!
If I had one of those laser boxes as a teenager, I would have another reason not to leave my room. Thank you for these videos, it's an oasis of edutainment in the literal and figurative desert I find myself in all the time.
Love your videos even though I don’t understand quite all of it. Keep up the good work :)
Very interesting! When the beam moves around the laser sensor you'll get a much higher false reading. So chances are the laser projectors are actually within spec. Try putting a lens in front of the sensor to focus it into a smaller dot size and that should help give you a more accurate reading.
Very insightful, I'm jealous and want one now.
You could do a demonstration on how light pushes objects with the laser cube. I know there's countless videos of it out there, but you could get some neat shots of it, especially with such a powerful laser. Possibly even do some investigation on the acceleration it induces with different settings. I'm very curious
awesome looking patreon bit
That laser cube sounds interesting. What I have is a laser Christmas display LOL. The bottom feeder of the laser chain ha ha ha Rock on dude! I love your display style for presenting science.

Even better if you have some way so that you get credit for the item if I buy it.
Thanks.
*I used to work for GRASS America (Austrian company). You should do a vid on their Cabinet Door Magnets that won't Slam Shut, but will draw themselves closed. Their construction is absolutely brilliant.*
There's a 2W laser cube available now that I would love to see another video on.

The lasers are amazing!
like this video!
i just was wondering, when it comes to the safety glasses..i was at my friends place and he had some, but they were like 15 nm lower then the laser he was using, does that matter? should you make sure the glasses stop the same number thats on the laser your using or will it be okay?
fantastic laser.
good choice for my cat
Noooooo. Don't give one of these to your cat. I made that mistake. She accidentally aimed it out of the window and managed to illuminate the cockpit of an aircraft coming in to land at the local airport. It crashed, killing all on board.
She got no treats for a week!
@@bdf2718 Castrations with lasers ;-)
Surprised they didn't use the now surplus heads from the pico projectors.. The mirrors move fast enough for raster scanning. Watching movies projected in laser light is still the coolest 🍺
I haven't been able to find any information on the heads based on the part number. Heads fast enough for raster scanning must be crazy fast! I thought they only used laser light instead of a lightbulb in video projectors - not actually scanning the focused beam... The more you know :)
@@brainiac75 The speed is achieved by smaller mirrors and are moved in a similar fashion to an optical pickup in a DVD drive, is magnetic field and no rotating parts.
Micro vision was the first with the showwx laser pico projectors, later they did an HD version, and Sony had a contract with them and Sony has their own laser pico projector..
There are also larger high lumen units with short throw optics for home theater..
If you don't mind the laser speckle, they produce the sharpest and most vivid colors I have ever seen.. Great with animated films..
The projector you're referring to are the laser hybrid dlp projectors that use a 450nm light engine and a phosphor color wheel. All fun toys to have in the collection 🍺
On the laser cube there was gain potentiometers. Perhaps you can calibrate the color of the output to be closer to white?
on your beam quality experiment on the cd holder it is actually very good data shows a very Gaussian beam (circular) for the 2 watt laser dock , this is do to the optical path of a strait through OP vs a 45 degree bounce off a short wave pass long wave pass filter can can add out of band harmonics
You should do a short video showing the galvos moving slow enough so that you can see them move.
I just love how the music changes from calming while testing the 1W laser dock into some frightening serious music while testing the 2W laser dock 😂
I love the laser vids
can one or more laser to light up evenly on a 3ft X 4ft X .2" flexiglass or similiar with short distance or on the side.
Thought this was a collab with What's Inside?. Nope! But that's fine. It was all cool.
Would like to see what's inside those lasers they use at Festivals, such as the massive TRANSMISSION TRANCE LIVE EVENTS.
is there a guide on how to build one yourself? i would like to use a 20kpps xy galvo and just a 1mW laser..
I think the less powerful laser may have burnt quicker as it might have more UV and Infrared coming out. More expensive lasers filter this better. You could prove this with some filters
There is no UV and i would be very surprised if wicked is still using dpss for the green. The site doesnt state wavelengths but does say pure diode so shouldn't be any IR either
Every green laser I have ever tested always leaks IR, Good ones only have small amounts but cheapies leak pile of IR. Some blue lasers are known to leak UV too.
@@Robonza Green diodes don't. Red diodes don't either.
Blue MM diodes have some IR up in 800nm, I have measured that on many diodes from 1-6W models over years from Nichia. No UV...
Only lasers I know of with UV and blue are He:Cd gas lasers that have deep blue and UV lines.
@@N4CR5 how much ir have you measured form the blue diodes? Thats very interesting. I wonder if its coherent ir.. i would think the dimensions of the quantum well structure would be all wrong for the production of a wavelength so far from its designed output Wavelength.
@@2smoker64
I'd hazard a guess you're right re:structures and coherence. I'll try a distance test next time I'm in the lab, that said lens will focus differently at another wavelength so it won't be perfect. Might chuk results on LPF, PL is dead.
It was typically a few percent of the output, under 5% at any output power. Wide band maybe 10-15nm wide. Can't remember if it was 808 or 880 though >_< sorry
Which one can be used to project a show on the side of a nearby skyscraper?
Have you tried to gain the laser diode using the rgb driver board? Would it be possible to juice the Red And green color up?
"X-Y Galvos" aren't these lasers made in Lithuania?
Very nnice content !
Are there any laser show projectors out there with specs safe enough to project around people without the worry of burning their retinas? I heard
Not really, most commercial ones range from 2w-30w, instead, you have to manually lower the brightness in software, or install a lens on the laser aperture to spread out the beam more so less energy is on a small spot. There is also a ton of permitting and approvals needed for audience scanning in most countries. The IDLA has a lot of good material on this.
My guess is the laser that created the smallest hole will perform over spec. A smaller hole means a smaller beam which is a higher power density at the focal point
I really like the modular design and the simple internal structure. However I find it kind of sad to see chong capacitors in such a high power edge-designed product.
It looks like the obvious design. 3 modulated lasers combined with 2 dichroics, then steered with a pair of galvo mirrors.
The third dichroic is likely to help with the fact that gas lasers (HeNe) have emission lines, unlike diode lasers. Assuming the red is HeNe.
no these are all laser diodes, even though your right tuned to what ever the diode power compared to the other drivers but around 650 nm not 632.8 as a helium neon , they have to be very very close to the resonant frequency of the mirror set as he stated in other videos, depending year of manufacture for the diode lasers
You have some cool lazers :)
Whats inside it? ,that's easy
*BLINDNESS*
Danke!
You left the single beam protection switched on. While you try to measure this way, you get a result how the filter protect the enlightened material with more half second, but no real data from the power, and you tried to compare them. Then you put a plate directly in front of the laser about 5 cms, this movement can harm your camera and laser itself, with the reflective energy. A single presentation projector can be harmed this way too.
Search for the OpenLase Project from Marcan and try to make your own laser projector. Would be a nice Video.
Well, I'm kinda glad i didn't spring for one of these. Nice effects, but i had been hoping for a couple of tiny troglodytes (kobolds, specifically) waving laser pointers at mirrors
Hey, I know one can make a laser power meter from a Peltier cooler all by themselves; is there any significant reason or scenario where a commercial meter would be much more preferable? Do I understand correctly that your meter that you show in the video is also based around a Peltier cooler element?
Hi, I haven't experimented with home made laser power meters, but the main problem must be calibration. When is the output from the peltier cooler equal to eg. 100 mW laser light? You can of course compare your lasers relatively with a home made LPM, but you don't know their exact value.
It is an interesting topic, and I may experiment with home made methods myself. Even painting the bottom on a normal thermometer black and pointing a laser pointer on it, should give a temperature rise proportional to the lasers output power. But precise? Not very likely :) Thanks for watching!
@@brainiac75 thanks for quick answer! You know, I actually have been experimenting with homemade peltier meters myself, and calibration is in fact very easy - peltier doesn't care where the heat/power is coming from, so you just stick a couple of resistors on it with thermal grease, more or less insulate them from the environment with styrofoam, and you have yourself a source of known thermal power for calibration (voltage squared divided by resistance). From what I've done I got a very linear calibration curve with about 20 data points, then I measured the power of my chinese 100 mW green laser with it (having blackened the peltier with soot from a candle), and I surprisingly got 95 mW measured value! The only problem is that it's the only laser I have; but you could possibly swoop through your whole array, I think that would be a heck of an interesting video, comparing commercial and homemade meters. Also I got this idea from the site "laserkids", look it up, the process of assembling and calibration is described there in full detail. Looking forward to your future videos!
Can you please do some double slit experiments with your awesome lasers?
Thanks for the suggestion. It's added to my very long to-do list. I'm not gonna run out of video ideas for a while just based on input from dedicated viewers :D
4:24 why didn't they just use an opaque mirror for the red laser then?
I just got my first LaserCube (2.5W Pro) a few days ago. Wonder how I could miss this, because I experiment with and build my own lasers for years now (have over 200 lasers in the next 10m around me, including self built arrays and up to 120W optical out). Just the day after I came across the LaserCube I ordered one...!!
Since then, I watched dozens of videos on the topic, and learning the differences between the different hardware versions. "Later" is not in any case "better". For example the beam quality seems higher at the initial versions, having to to with the laserdiodes they sourced (single mode vs. multi mode; later versions therefore use corrections lenses to compensate that). What I have to highlight: The support from the guys behind LC is really good. I got fast and detailed answers from them to a few questions I asked. Very helpful! I'm very curious what further improvements they have "in the pipeline"! Chances are high I will buy it as they release it... :)
What I wanted to ask you, because I've seen that in a few of the LaserCube videos here on TH-cam, but no one seems to mention it: The 1W LC seems to project a point in the center of the picture from time to time. Visible for example at 09:10 projecting the dancer. The other device, the LD, does not. Is this related to the 20K galvos of the 1W? Or any other optical reason?
Also thank you @Brainiac75 for your very informative and nicely made videos, I like them a lot!
Cool!
Once I bought a cheap green laser pointer. I think it has about 0.2 - 0.5 W, but seller stated it has 50W! I am not a expert on lasers, but how powerful will the 50 watt laser be?
If it really looks like a 50 W laser, for the love of god dont turn it on without extreme care. Thats laser cutter territory.
@@TheBackyardChemist Well it is 10$ chineese laser, I was just wondering what would it be if it had 50W
Please provide me the link for me so I can buy the 2.2W Laser Show product.
Why and how did I think the electricity warning sine was for lasers
These aren't RGB diode drivers-these are buck boost converters to create stable dc voltage and it PROBABLY wasn't rider for those salvos it was PROBABLY stepper motor driver (not sure:/)
Big yeet
Where Did you get that cube I want it
At least it's not 1W Glue.
The dichro mounts look like a recipe for dealignment though. Cheap nasty stuff for a pro user but ok for beginners and enthusiasts.
Some in-house AT laser scanners? Definitely low end but acceptable for beams.
LiPo for?
DIY is always best of course for enthusiasts ;)
CD case test isn't scientific because beam quality/focus/stacking/alignment make a difference there.
"Burn tests" scale with intensity, not power.
@@RealNovgorod
Indeed, intensity is influenced mostly by the parameters I mentioned which are most applicable to this test. Should have added beam diameter also.
1:00 FULL POWER? What about all 3 lasers in 1 spot at once lol?

Very interesting comparison. I was slightly disappointed that you didn't try harder to compare apples with apples in the brightness comparison for example with fixing your camera's exposure setting, but I guess it wouldn't have looked much different to the results that you did show, so just me being petty. And possibly expecting more based on what I've seen from your previous videos... maybe...
Thanks for the feedback! The comparison clips were shot in a daylight lit room with the exposure turned way down (f11 is the lowest on my video camera). Going lower in exposure, I would have to dial down the exposure time. And filming a laser show with short exposure time on a rolling shutter camera is a flickering disaster - way worse than what you see in the video. Send me a camera with a global shutter, and I probably could do better ;)
The point is though, that no matter how I set the exposure on the camera, your screen will not give the same brightness experience as seeing these in real life. Thanks for watching!
@@brainiac75 ok you're forgiven. The flickering will be painful. Question... You're referring to exposure but mention an aperture setting of f/11. I am more experienced with still photography than with fancy video work, but I wonder whether a stills camera set to full manual: known preset aperture, ISO and slowish shutter speed on one of those fixed type laser images won't illustrate the difference better than a video. Just me thinking out loud.

i think the laserdoc almost 500, and the lasercube 600. but the laserdoc you will need software, the lasercube have the software inside when you pay 600 youre done. and the laserdoc is 500, and you need software the cheapest software is 200 youre pay then 700. go for the lasercube
@@MrDutchpiet Thanks!
@@henrykoplien1007 no problem i had the same problem i buy the laserdoc, the laserworld 1000 rgb, it has 30 patherns in auto mode, if you want change the patherns you need a dmx of software. its really sucks. i send my laserdoc today back to the webshop, i go for a cheaper laserdoc on alieexpress, i can controll it with bluetooth thats okay. but the lasercube is a better choice its have software inside you can control it with your phone, and it have almost the same mw for all lasers as a laserdoc you have more options. go for the 1 watt its dangerous enough
