This letter reports the observation of one- and two-dimensional amplified spontaneous emission of F+3 color centers in a LiF crystal and a measurement of its optical gain coefficient.

We report the experimental observation of nonlinear optical phase conjugate (NOPC) effect caused by the resonant saturable absorption of F 2 - centers in LiF crystals. The experiment was performed by making use of degenerate four-wave mixing in the laser cavity. We also give the curve of the phase conjugate reflectivity versus the incident energy of the probe light.

For the first time a persistent spectral-hole burning stable at room temperature was realized in LiF crystals with F/sub 2//sup -/ color centers. The Huang-Rhys factors and zero-phonon linewidth of F/sub 2//sup -/ color centers were studied at 14-350 K temperature range.
