black is absence of light, and lasers are light amplification. so it is impossible to have a black laser.. well......... not impossible, go buy any laser, take out the batteries. then when you push the button you got a black laser.

You can also achieve this effect by aiming the laser at your face instead of a wall. :)

no joke -- that's actually the exact amount (well actually 10 because he misspelled one of the words to form a completely different word on accident...)
:rolleyes: kids these days

Here are a few shades. Should be about 500mW.

that's funny and all (even though I've heard it before) but actually if you wanna get technical, you're wrong. The word 'laser' means (or rather, is an acronym for) 'Light Amplification by Stimulated Emission of Radiation'. Now explain to me how a laser with no batteries is gonna do that :p

but you gotta admit it would be the sh*t to have a 'Black' Laser ;)

Actually that's in interesting idea... anybody know the wavelength of light for a black light?

There Is No Spoon.

Some argue that IR light is "white" while UV light is "black". But the ideas with colors is that black and white are not actually colors. They do not by itself contain color pigments of any sort.

Black is "produced" by absence of light, and white is produced by combining frequencies (remember those school prism labs?).

The bottleneck here is how your taps in your eyes perceive frequencies.

Black lights are UV. They don't emit just one wavelength. they have a peak wavelength of course, but searching a bit looks like it's an up to 50nm wide band of color being emitted. and the peak wavelength will vary from one black light to another as there is more then one phosphor used in black lights. Seems the area with the most overlap looks to be 350-420nm Any way you spin it, given that black lights are in the near UV and violet range, you could easily make a case that a BR is a "black laser"

I know Black Lasers are almost impossible to make due to gravity related manufacturing restrictions,... but not impossible Imagine,... it's a sunny day and sudenly you see a black laser beam coming from the other side of the horizon. If you zoom into the the sky you can see that we are surounded by dark matter 24 hours a day,... In this dark matter the sun, the planets, stars etc. looks verry small compared to the volume,... of the dark matter. Isn't that incredible ?

Not "almost impossible", impossible. What part of impossible can't you comprehend?

Can't be build on this planet due to gravity related manufacturing restrictions. You will have to wait untill space travel becomes more cost effective so you could setup a lab in a antigravity environment :umbrella:
