Closed-Cycle Rare-Gas Electrical-Discharge Laser

Abstract

The recently developed technology of high-pressure molecular lasers has been combined with ultrahigh-vacuum technology to develop a fast-flow high- pressure laser system capable of long-duration closed-cycle operation with rare gases. The system has been used to investigate laser media excited by short, fast-rising high-voltage pulses under conditions of high pressure, fast flow, and low-background impurity level. Experimental results of parametric investigations of high-repetition-rate laser performance for Ar-Xe and He-Xe mixtures are given. Ultraviolet photoionization characteristics of molecular lasers are presented. The photoabsorption cross sections and photoionization yields of N,N-dimethylaniline, triethylamine, trimethylamine, and tri-n- propylamine are given and their use as laser seed compounds discussed; nitric oxide is also considered. UV emission spectra of spark sources applicable to CO and CO2 preionized lasers are presented.
