i had an epiphany, what would happen "if anything" when you view a laser under a black light? because i know that your skin looks different and white shows up allot more. may be a pointless post or a whole new discovery! ;D

A black light is essentially ultraviolet light right? A black light would reveal nothing new, it would only light up florescent things (like a bluray). A combination of the two would be sadly uninteresting.

In theory though, wouldn't the florescence from the BR mix with the florescence from the blacklight thus making the dot hard to or impossible to see when they're on the same thing? If they're both florescing at the same wavelength, it's feasable...

More likely, the beam will magnify in brightness when it is ADDED to the blacklight??? this is a question for the pros. just a newbie educated guess. ;)

ehh i see, well im going to do some experiments with my black light, smoke machine, and my laser when i get it ;D

The BluRay does not fluoresce... there is nothing to fluoresce. It causes fluorescence in other objects, so what you would see would be the dot would change colour to whatever colour the object it was shone on appeared under blacklight!

If you used a BR in a room with a blacklight, you will still see the BR dot, since they are different wavelengths.

It wouldn't magnify in brightness just like a red laser wouldn't in a room with red light.
Anyway, how does the wavelength of the bluray compare to that of a blacklight bulb and those violet LEDs?

Violet LEDs are ~395nm I believe. Black lights have a few emission lines, most in the UV range but a few in the violet area as well. Since both violet and ultra-violet will fluoresce, the only difference in appearance really would be the apparent intensity of the initial beam. 360nm looks like an extremely dim blu-ray, just as 808nm looks like an extremely dim DVD diode.

The blu-ray's dot will be quite a bit brighter.

and what is that exactly? because its a blue laser with a green leftover residue trail?

I think it's a blu-ray on a glow-in-the-dark T-shirt.You can see a bright blue dot probably because of the fluorescence or the camera.Short wavelengths like blu-ray or blacklights do a very good job of "charging" glow-in-the-dark stuff :D
