red lasers CAN write GITD (kinda) :D

so i discovered this little thingy with red laser
ofc when u point reddie to GITD surface it doesent react...BUT when you charge GITD with a flashligth (or something else)and THEN point reddie to surface it "turns off" from that part where red hits:drool:
anyone else fount this???

Weird. I've never thought of doing that before... got any videos?

Awesome discovery!! I heard about this with IR but that is great that it works with red as well. I cant wait to try it out.

yeah its amzing
i have a theory too for this....maybe......if uv charges it and it starts to produces specific wawelength(seeable by human eye) so then when you point red laser to it it productces maybe some else wawelength(not seeable by humaneye)
does this make sense?

Try looking at the red/IR charged surface with a digital camera that sees red.

It may confirm your idea.

not ir(camera sees no ir) but maybe some wery long or short wawelength

Or the red is acting in a way that makes the excess energy released by heat instead of light. Or maybe it accelerates the energy release.

I've tried to reproduce the experiment you shared with us but I can't see the same results, care to post a video on how and where you did it?

sorry my laser has so damaged lense so it disables almost whole(even focuced) GITD object (10cmx5cm) :( if someone can do same as me could that someone post video :)

I've always thought this was a cool trick, I like to use a UV flashlight on a GITD surface and then use a red pointer as an "eraser" on the freshly charged surface. Once the surface isn't charged anymore, the red will slightly charge the GITD surface.

Its the stimulated emission part at work here - you can 'darken' any glow in the dark surface/material by exposing it to the wavelength it roughly emits.

So, would a greenie be better? Presumably the highest frequency that doesn't charge it, discharges it fastest?

i dond have greenie to test it out but if someone who has greenie and red would compare
btw that theory erally makes sense...maybe:thinking:

Yesterday I was playing with a childrens toy consisting of a glow in the dark sheet and a pen with a UV LED in the tip. I charged it up with the UV and hit it with my green laser, and it did quench the phosphorescence. I don't know if this was due to unfiltered IR, the green, or both, but it seems that any photons of sufficient energy to quench, yet not high enough to charge should work, no?
