Red Glow In The Dark (very dim)

I put my recording device behind some protective glasses to film my Glow In the dark board with my violet laser pointer, and something really cool came out.

Basically the green light becomes red.

Depending on the power and glasses the color will vary. My Argon glasses show an orange dot while my cheap ones show a violet beam, this is for my 445nm and 405nm. I havent been abe to find my 5mW green to test it out though, might have to buy another one soon.

Virtually any "green" light source will have some red component. For example, here's a green CCFL, followed by a green tritium vial, followed by a lime-green LED:
