Paper Abstract

Laser-induced breakdown (LIB) thresholds in AgClxBr1-x crystals and fibers were studied under CO2 pulse and cw laser excitation. The dependence of the LIB and IR absorption on composition and temperature treatment suggests, that the LIB in silver halide crystals and fibers is due to the absorption at 10.6 micrometers caused by cation vacancies bound with charged dislocation silver halides. The lower optical stability of the fibers is due to defects induced by the heating under pressure, applied during the production of the fibers by extrusion and the subsequent fast quenching to RT. A simple method for reduction of the IR absorption is proposed.
