Laser technology, all about lasers

Laser microphone to detect sound within a room (having an outside window) at a distance. The principle being that sound vibrations will cause the window glass to move sufficient to deflect the LASER beam across the receiving photo detector

Lasers a LASER (Light Amplification by Stimulated Emission of Radiation) is an electromagnetic oscillator which combines light amplification with feedback. The laser uses mirrors to feed the light output from an optical amplifier through a delay (the travel time of the light) back into the amplifier input

Semiconductor lasers pdf file

Semiconductor lasers the semiconductor laser is a laser in which semiconductor serves as photon source. Semiconductors (typically direct band-gap semiconductors) can be used as small, highly efficient photon sources. Such semiconductor photon sources find application in displays, optical storage, communications, printing, surveying, and as small efficient optical pumps for other optical processes
