Description:
Incorporation of acousto-optical tunable filter (AOTF) in cavity of solid-state laser, provides means of adjusting wavelength of laser output electronically, according to recent proposal. Output wavelength randomly selected in microseconds. Technique useful in remote-sensing applications, such as in differential-absorption lidar (DIAL) and in communications for wavelength-division multiplexing.
