Abstract

An SF 6 gas calorimeter has been developed and used operationally in a large aperture, multijoule, short-pulse, CO 2 laser system. Pressure rises rather than temperature rises are measured in the absorbing cell. Measured pressure sensitivities of 20 pascal/joule are in good agreement with the calculated values.

Abstract

Short‐pulse energy extraction measurements have been made on the Los Alamos Scientific Laboratory three‐stage amplifier system. The energy extraction from one, two, and all three stages was found to be in excellent agreement with a rate equation theory including rotational relaxation and beam expansion. Amplified pulse energies of up to 20 J in 1.5 nsec were obtained.
