Turnable Blue-Green LIDAR Transmitter Demonstration: Injection Laser Technology

摘要

Rice University and United Technologies Research Center have collaborated on ascaling demonstration of the tunable, blue-green XeF(C-A) excimer laser focusing on the general requirements of a sensor for optical discrimination applications. Under separate contract Rice developed a scaled, repetitively pulsed XeF(C-A) laser amplifier, while under the present contract UTRC developed a wave length-agile dye laser as a source of injection control for the Rice amplifier. In late 1989 the UTRC injection laser was successfully integrated with the Rice XeF(C-A) amplifier, resulting in wavelength-agile XeF(C-A) laser operation at the 1 J/pulse level, combined with an intrinsic efficiency > 1% and a pulse repetition rate of 1 Hz. Random sequence wavelength agility on a pulse-to-pulse basis was demonstrated over a 20 nm band, and an over-all efficient tuning range approach 50 nm was demonstrated. This final report covers the UTRC portion of the program, wavelength-agile injection laser technology in particular. Keywords: Scalable blue green lasers, Optical parametric oscillator. (KR)
