Lasers are known to emit a particular wavelength, and with a bandwith that is extremely narrow. I have been told that if a laser medium is white light, such as the light from HID lamps or flash lights, the laser will amplify just one wavelength. Is this correct, or is it possible for a laser to amplify several wavelengths at the same time? If not, why can"t a laser amplify white light (or several wavelengths)?
I am thinking of if one placed parallell mirrors on each side of a tube containing the same gas as inside HID lamps, and power it up.
