      What would happen to a normal extractor fan on the wrong voltage ?
      Can you show us what would happen ?

Thank God there are people with brains producing content for this site, as it stands TH-cam is becoming a babysitter site for under 2 year olds entertained 24/7 by iPads. Children who don't play with toys but only know how to swipe on a touchscreen. It's a terribly sad social experiment.

      ***** I'm very selective in who I watch, but when it comes to a strip down like this you're showing stuff that's never properly explained. Not every day you get an insight into this sort of machine from someone who knows their craft. I'm not after the free HeNe giveaway, I just love the free info. Sadly Lasers where live have basically been banned.

    Photon, you need to go to the BBC and get a TV series made around subjects like this. The way you explained how it works was a lot of times way above my head but if you had had a show where you allowed average intelligent numb nuts like me to even half understand how electronics work I think you would be bigger than Jeremy Clarkson. Love you work and makes me want to go to my man shed and destroy stuff.

      HeNe is so obsolete... those diode lasers runs on batteries and does the same thing. I seen a video about the first CD players, and they were quite large because they used HeNe lasers or something of the sort (actually CD players uses infrared lasers, DVD uses red lasers). Now with laser diodes you got really tiny CD players that can fit in your pocket. But who needs optical discs or even bluray when you got solid state memory?
      By the way when I was a teenager, back in the 90s they were saying how blue or green laser diodes had to be cyrogenically cooled and all that. Now we got bluray lasers or laser diodes that didn't need DPSS setup or anything. You gotta thank quantum mechanics for this as these diodes are made due to some quantum tunneling principle. I think not long after gas lasers will likely be rendered obsolete because gas lasers often require cooling, especially for higher power applications. Like the K40 laser, requires an aquarium water pump to run water through the tube at all times.
      I imagine in the 80s if they had a laser pointer it was a big freaking thing that needed fiber optics to work as a laser pointer.

    It's always fascinating to see a complex machine taken apart, exposing its inner workings and components. When something like this laser is fully assembled, to the layman it can look like a mysterious and incomprehensible thing, but once you bust it open, it's "just" a lot of circuits, metal bits, mirrors, and a crystal rod, which makes it all the more amazing to see what it's capable of.

    Andy, LASER is "Light Amplificaion by *STIMULATED* Emission of Radiation" - notice my accentuation of the word *STIMULATED* - you said "simulated". I am sorry if I sound pedantic, but a *simulation* in place of STIMULATION, wouldn't do a thing.

    I *think* the copper box became oxidized like that because the cooling system was ran on regular plain-ass tap water. It's the same thing as with PC liquid-cooling systems : you would never run H2O through it since it eventually eats away at all metal parts, especially if the system contains parts made of different metals, since galvanic corrosion would occur (I think that's what they call it).

    Its funny how that goes from one extreme to the other - the HeNe (no not chasing it, I already have one, give it to someone else) with its little 12V brick supply, and no cooling what so ever, to the ND:YAG that kept it company that uses 100's of volts, water cooling, air cooling, and generates 100 watts+ of infrared light. 3 cool light sources in one box. I was expecting to see a medical grade isolation transformer in there as well :) Great video as always. Thumbs up :)

    I have an SSY-1 Nd:YAG laser rod of about the same size from a tank rangefinder, but it is pumped with a flash lamp instead of a water-cooled continuous lamp.
    I am in the process of getting even more capacitors for a power supply from Walgreens disposable cameras (you can get those for free, they throw out the cameras once they take out the film) so I can power it in pulses. My unit, when done, will be handheld and in the format of a laser gun. The pulses are about as powerful as the laser you are using, but they only last for a fraction of a second.
