Abstract
The one and two-photon spectra of $NaF:Cu^{+}$ showed a zero photon line and a progression of the $t_{1u}$ mode $(Cu^{+}$ moving off-center) in the $^{1}A_{1g}\rightarrow^{1}E_{g}, ^{1}T_{2g}$ transitions at $2^{\circ} K$ . the spectra have been fitted with a 3-dimensional mixed quartic-harmonic potential including a crystal field term. The increasing widths of successive members of the progression are related to the increasing density of states of the NaF lattice. Coupling of the $t_{1u}$ mode to the Jahn-Teller potential in the $^{1}E_{g}$ state has clearly observable effects. Other aspects of this unusual example will be discussed.
