Scalable nanosecond CO2 laser technology
Abstract
Small signal absorption measurements over the 9 and 10 micron bands were carried out on various molecules to determine their potential as gain isolators. Saturation and relaxation experiments are being set up to further evaluate some of these absorber media. Theoretical studies are providing the necessary inputs in various molecules. Flowing saturable absorber device, the flow field structure of gain and absorber regions, was studied. A species concentration probe is being built to determine the amount of contamination of the gain medium by saturable absorber medium due to mass diffusion in the mixing layer. Nanosecond CO2 oscillator to conduct saturation experiments of candidate saturable absorber media under both single and multi-line conditions was also considered.
