increasing wavelength? Answered


Is it plausible to increase the wavelength of, say, infrared light? I have a 808 nm 1 watt laser and i am struggling with researching if it is plausible to do so, and if it is then how it would be accomplished?

How much? If you increase it very much it wouldn't be IR anymore, would it?

Increase ? There are non-linear crystals that will DOUBLE your optical frequency, I'm not familiar with ones that work the other way.
