A computational approach has been formulated to predict the average pulsed power output of a continuously pumped Q -switched YAG:Nd+3laser. Using this technique the dependence of laser operational characteristics on parametric changes can be readily evaluated: Q -switch mechanization, optimized output coupling reflectance, effects of intracavity losses, and pumping efficiency on average pulsed power are some of the more important items. This theory was checked experimentally using a 10-30-W multimode and 1.4-W TEM00mode laser operating at PRFs between 1 and 40 kHz; excellent correlation has been obtained.
