Abstract

Stable operation of a 1.2 As pulse, high energy, electron beam pumped XeCl laser at a bandwidth of 225 MHz has been achieved. This bandwidth is obtained without external injection by utilizing the self-regenerating feedback from a portion of the broadband laser output that is filtered through a series of Fabry-Perot etalons in a retro-ring configuration. The laser is a positive-branch confocal unstable resonator with a typical narrowband output of -20 J. The laser comes under narrowband control after -200 nsec and has a wavelength tuning accuracy of ± 50 MHz. Polarization locking achieved by this system is quite efficient, producing typical locking ratios of S-to P-polarization of > 100:1. The narrowband output is analyzed with a 1.5 GHz confocal etalon and a streak camera.
