An experimental investigation was made of the spectral characteristics of radiation emitted by a YAG:Nd/sup 3 +/ laser in which an LiF crystal containing F/sub 2//sup -/ centers was used as a passive switch. Single-frequency emission and mode locking operation regimes were investigated. In the single-frequency regime the minimum width of the emission line was 5 x 10/sup -3/ cm/sup -1/ for a single pulse. The frequency selection mechanism involved spatially inhomogeneous saturation of the absorption. Mode locking took place in a ring resonator when a saturable crystal filter with an initial transmission 0.7 was used. The use of a switch containing color centers made it possible to generate picosecond pulses simply and reliably.
