Laser-induced breakdown (LIB) thresholds in AgClxBr 1-x crystals, polycrystals, and fibers were studied under CO 2 pulse laser excitation. The limit value of LIB threshold P c of the bulk crystals is about 4×108 W/cm 2 for x=1 and 8×108 W/cm2 for x=0 under 100 ns transversely excited atmospheric pressure laser excitation. The LIB threshold in fibers is much smaller; about 2×107 W/cm 2. The dependence of the LIB on composition and temperature suggests that the main cause for LIB is electron avalanche combined with multiphonon absorption at 10.6 μm in silver halide crystals.
