Paper Abstract

A series of sixteen diagnostic experiments were developed for the Laser Scaling Evaluation Program (LSEP). These experiments, along with a data acquisition plan, provide the basic information required to scale from moderate power to high power CW chemical lasers, and represent a reasonably complete set of typical experiments for all CW chemical lasers. This paper describes the experiments, which include measurements of gain medium optical quality, small signal and saturated gain, output beam spatial and temporal polarization, beam centroid and beam quality, spatial phase map, near-field and far-field intensity profiles, homodyne spectroscopy, mode shape, spectral content, total power and power as a function of time with high temporal frequency resolution (P(t)), cavity pressure dynamics, and mirror accelerations. The plan for processing the various data and the expected processed data are also discussed.
