Paper Abstract

Experimental research for high energy lasers is currently accomplished with large volume CO2 flowing gain cells and unstable resonator mirror configurations which often include conical optical elements. There are a number of diagnostics available throughout the HEL community. However, there has never been a complete comparison between theoretical results and experiment, because of the limitations in diagnostic equipment and the complexity of current resonator designs. Analytical and numerical models for CO2 gain cells with unstable resonators also have limitations. As experimental configurations and theoretical models increase in complexity, comparison between the two becomes increasingly difficult because the number of variables is too large. In this presentation, we discuss the unknown variables and problems in making a complete comparison. A list of available diagnostic equipment and its limitations is presented. Some results from analytical and numerical models are compared to data. Finally, a summary of requirements for obtaining a reliable and complete comparison between experiment and theory is given.
