Abstract

A multi-component gaseous saturable absorber has been developed and modified to prevent the onset of parasitic oscillations coupling laser-fusion targets and the power amplifiers in the Helios CO2 laser system. This absorber mix greatly increases the extractable short-pulse energy of the laser system. A computer model that predicts the behavior of multi-component saturable absorbers has been tested against the measured performance of two different absorber gas mixes used in the Helios system. The successes and shortcomings of the model are discussed, and large and small-signal transmission data for the saturable absorber mixes and their constituent gases (used as input to the model) are presented.
