Abstract : The report describes the results obtained in the development of a high average power optical radar transmitter operating at 1.06 microns employing a master oscillator-power amplifier approach. The master oscillator was a mode controlled, water-cooled, pulsed device employing glass:Nd as the laser media. The amplifiers were water-cooled and operated under pulsed conditions and also used glass:Nd as the laser media. This approach yielded average powers of approximately 10 watts, i.e., 10 joules per pulse at a repetition rate of 1 pulse per second. This was accomplished without any degradation in the transverse mode characteristics of the oscillator signal. Based on these results, it is estimated that pulse energies of 50 joules could be readily achieved at 15 pulses per second, thereby leading to average powers of approximately 750 watts. (Author)
