Paper Abstract

This paper describes flow techniques developed recently for pulsed chemical laser applications. These techniques support development of a high power, repetitively pulsed DF chemical laser that has high beam quality and high mass flow utilization, and eliminate flow issues as major technical obstacles to such laser development. Three coupled flow problems are identified, and mutally compatible solutions to these problems are described. These problems are 1) extinguishing chemical reaction following each laser pulse (i.e. "flame-out") so that fresh D2-F2 mixture can flow into the cavity, 2) supplying a homogeneous reagent mixture with the required 99% individual species uniformity, and 3) rapid suppression and clearing of pressure disturbances produced by pulsed reaction to provide required density uniformity in the fresh mixture.
