Abstract

A comprehensive computer code has been developed to analyze output performance of KrF laser excited by an intense electron beam. Especially for short pulse ( less than 100 ns) and high excitation rate ( greater than 1 MW/cm**3) pumping, and under realizable conditions, the intrinsic laser efficiency has been calculated as a function of excitation rate. The results are compared with some experimental results which have been already reported by other groups, and a fairly good agreement is obtained. At an excitation rate of 1. 5-2 MW/cm**3, and at a total gas pressure of near 1. 5-2 atm, an intrinsic efficiency of up to 11. 5% is found to be attainable. At 3-4 atm, even at an excitation rate of near 7 MW/cm**3, an efficiency of 9% is obtainable. The KrF production efficiency and the laser extraction efficiency have also been calculated, and the output performance is explained in terms of excitation rate.
