Characteristics of 355 nm Laser Damage in Bulk Materials

The laser damage resistances of four crystals (CaF sub(2) MgF sub(2), Al sub(2)O sub(3), and SiO sub(2)) and fused silica (JCS1) irradiated at 355nm (8 ns, 300-on-1) are reported. The laser-induced damage threshold is measured using a tripled Nd:YAG laser system. The results obtained from the pure c...

Description
Summary:The laser damage resistances of four crystals (CaF sub(2) MgF sub(2), Al sub(2)O sub(3), and SiO sub(2)) and fused silica (JCS1) irradiated at 355nm (8 ns, 300-on-1) are reported. The laser-induced damage threshold is measured using a tripled Nd:YAG laser system. The results obtained from the pure crystals are in accordance with their specific optical, mechanical, and thermal properties. An empirical law based on the Franz-Keldysh effect can interpret the experimental results
