The molecular charge transfer states of Cl-doped solid xenon form an ideal four-level laser system. UV excitation on the molec-
ular XeCl (B+X) pair potentials leads to the formation of the diatomic exciplex which relaxes with a nearly unity quantum yield
to the triatomic Xe,' Cl- (4 `F ) state. The radiative dissociation of the triatomic exciplex can be stimulated to provide mono-
energetic atoms %1eV above ground. While these systems are characterized by large gain coeffkients, scattering losses predomi-
nate in samples prepared by standard matrix isolation techniques. Scattering losses are due to the inability of the lattice to
accommodate the excess kinetic energy released in the bound to repulsive transition of the triatomic exciplex.
1. Introduction
In a previous paper, herein referred to as I, we
reported on the spectroscopy of xenon chloride exci-
plexes in rare gas matrices [ 13. Atomic chlorine is
photogenerated cooperatively in solid xenon by UV
irradiation of matrix-isolated HCl or Clz. The dia-
tomic Xe+Cl- (B) state can be accessed directly in
the atomic solids by UV excitation of the charge
