[Guest]

Greetings, All

Has anyone tried using color gels like the one studio lights use to change the color of a laser?
Does it work?

Laser produces monochromatic light.

It would not work. Any filter, other than the color of the LASER,
would totally block the light.

Filters work with tungsten(and other) lamps because those lamps produce
light across a wide spectrum of visible "frequencies" (colors). LASERS
only produce one narrow band of frequency (color).

So lets see... Shine a pure red laser through a filter that only lets greeen
light through and you get what out the other side.. ?

Nothing. Absoulutely nothing. The red light waves would not go trough.
And a Red LASER is only red light, not any other color. LASER is special
_because_ it is only one wavelength already.

Correct. Give the man a prize
