Abstract
Energy extraction in XeCl discharge amplifiers is examined experimentally and theoretically for 0.16-, 3.0-, and 600-psec pulse durations. Saturation energies of 1.0, 1.0, and 2.5 mJ/cm2, respectively, are measured. When nonsaturable loss is included in the analysis the values of the saturation energies increase to 1.35, 1.35, and 3.0 mJ/cm2, respectively. A significant decrease in the effective small-signal gain is observed as the pulse duration decreases to the bandwidth limit, in agreement with a simple coherent pulse-propagation calculation.
