Abstract:

Beam jitter diagnostics were developed and tested on a repped-flowing CO2 e-beam sustainer laser cavity. The limiting source of jitter was found to be due to gas density gradients in the cavity. Both flow-induced gradients and disturbances from the repped discharge contribute. Reduction of the jitter magnitude can be accomplished through temperature control of the gas flow and acoustic suppression.
