Optically pumped laser action has been achieved over the XeF (B-X) and (C+A) transitions in crystalline argon. Conversion
efficiencies as high as 30% are observed. Gain measurements indicate that the laser should be tunable over the broad C+A band
of =80 nm.
1. Introduction
We report the first demonstration of an optically
pumped visible laser in a rare gas crystal. The sys-
tem, XeF in crystalline argon, is representative of the
large family of solid state rare gas halide exciplexes
which contains members suitable as laser candidates
in the visible, UV and VUV spectral ranges.
The rare gas crystals used in the present work were
prepared in the apparatus used by Schwentner and
coworkers in their effort to develop solid state VUV
