    Default Playing with blu-ray laser pointer

    Out of curiosity I aimed my blu-ray pointer at a CRT tv set and it caused a bright greenish-blue glow. Inspecting the glowing phosphors up close I found that the blu-ray wavelength produces a strong fluorescent response in the CRT's green phosphors, a moderate response in the blue phosphors and no response at all in the red phosphors.

    I've also found that it creates a striking but brief reddish-orange phosphorescent (after-glow) response in a rock that I have yet to identify.

    If you have one of these violet laser pointers, aim it at some rocks and see if you get a response.

    Yeah, I'm easily amused.
