Operating characteristics of a high repetition rate miniature rare-gas halide laser

Performance characteristics of a high repetition rate rare-gas halide minilaser are reported. At 1 kHz pulse repetition frequency over 1 mJ per pulse at KrF and 0.5 mJ per pulse at XeCl wavelengths are obtained. Net small-signal gains greater than 0.3 cm
^-1
are observed in XeCl. The wall plug efficiency is measured to be as high as 0.25 percent.
