Fascinating video! It looks like the infrared laser might be inducing a photo-bleaching effect on the glow-in-the-dark star. This happens when a high-energy light source, like your IR laser, stimulates the phosphorescent material in the star, causing it to release its stored light energy more rapidly. It's a neat demonstration of how specific wavelengths of light can interact with luminescent materials in unexpected ways. Thanks for sharing this intriguing phenomenon! ✌️❤️🪀
Any source of IR/deep red will work. I would say your best bet would be to try working with some higher powered IR LEDs, 1-3 watt beads will work very nicely.
Thanks! NIR glow in the dark stuff is something I haven't looked into before. Here is a link that might be useful. www.instituteofmaking.org.uk/materials-library/material/near-infrared-persistent-paint If you enjoyed this video there is a follow up on it on my channel going over more stuff like this. th-cam.com/video/75fleVQN4X4/w-d-xo.html
I think the reason why green lasers also work apart from IR ones is; green (DPSS) lasers are simply IR lasers with an optical "frequency doubler", so the wavelength changes from like 1060nm (IR) to 530nm (green). Cheap green lasers often don't have IR filters, so you get green and invisible IR radiation at the same time. Very dangerous if you have laser safety goggles for only green laser light and don't expect the IR radiation.
My hypothesis is that the larger IR waves push the smaller green and UV waves in the star outwards, kinda like when you have water with pepper on the surface and you drop a drop of soap over the water and it pushes the pepper out to the sides. I noticed the stars glow field also gets brighter around the forming dark spots. It's still really weird. I think you could even get rapid discharge off any IR source like a TV remote though I have not tried, maybe i will lol..
The IR light encourages the glowing material to release it's energy in the form of green light faster, this darkens the exposed areas after a short period of time as they have less energy than the surrounding material. This video has been up for a while so you've probably figured it out by now anyway.
iv only done like ir uv radio and all that in school one so im probbly wrong but is it cuz ir is longer than visible light and uv is shorter than visible light in wavelength? just guessing here lol probbly completeley wrong its just in my head cuz we just did the Electromagnetic Spectrum in school
May it be that the laser simply produces heat, which disables the dye from emitting light? How do those plastic star behave when heated e.g. with a hot tea mug is put on them?
There was a whole follow up to this in a laser video with phosphorescent phenomena where I do tests with hot and cold. You are correct in thinking that heat plays a major role in how the materials release their energy.
Are you talking about valance bands of electron shells? I am aware of that portion of physics, however why IR seems to cancel/move the light in the charged portions is still strange reaction, I have yet to figure it out. Large waves of light seem to knock the photons out of the chemical faster/push it outwards.

Interesting. I was searching for ways to discharge GITD material, so your video was helpful.

i was searching for "infrared-spectrum-emitting, glow-in-the-dark paint" for CCTV applications, and found this.
it is a very interesting phenomena.

would this be the same for IR bulbs?

It's just *IR Laser* not IR-Red laser, that's like saying, " Infra-red-Red Laser"
It is covering 808nm IR - 640 red laser light both laser color bands will have this effect.
Is this a serious phenomenon ?
Dont they teach kids about high/low energy orbits anymore?

Public schools do not teach anything of merit anymore. Their only task is to collect federal money based on the number of students in attendance.
Strange, I went to all private schools and they tried the same brainwashing tactics.
This is why I teach myself.
That in truth is the best way to learn.
its because the light is boring
Heated phosphorescent compounds release photons much faster. That's it.
If the laser was hot enough to make it warm, I would agree.
