Multiple Pulse Laser.
Abstract
The objective of this program was to develop the techniques necessary to implement a multiple pulse laser. The particular multiple pulse device chosen for the effort was a 1.06 micrometer, Nd:YAG, electro optically modulated laser that could generate bursts of 1 millijoule, Q-switched pulses at average rates up to 10 bursts per second. The pulses in each burst were to be 1 microsecond apart and a burst was to last for 100 microseconds. As a further goal, it was required that the bursts would be generated upon command using an external trigger, and the first pulse of each burst should be transmitted not later than 3 to 5 microseconds after receiving the external trigger pulse. The baseline, guide system chosen is the TVR (Time Variable Reflection) cavity. Although TVR lasers had been built previously, the stringent requirements of the multiple pulse format demanded the solution of three major technical problems: Controlled pumping, high speed modulator driving, and modulator crystal acoustic damping.
