Paper Abstract

Damage thresholds of bulk samples and fibers made of high-purity chalcogenide glass of As-S system for YAG:Er laser ((lambda) equals 2.94 micrometers ) are investigated. An accumulation effect is found both in fibers and bulk samples, which reduces stability of repetitive pulse laser operation. Correlation between damage thresholds and heterophase inclusion concentration has been observed experimentally. In samples with impurity concentration less than 104 cm-3 the damage thresholds exceed 1 kJ/cm2 for single shot pulse and approximately twice as low in the repetitive pulse regime. Fibers made of glass samples with minimum concentration of impurities are capable of increasing YAG:Er laser radiation power transmitted through a fiber.
