Laser Damage in Materials

Abstract

Neodymium:glass laser induced damage is observed in lithium niobate (LiNbO3), calcite (CaCO3), potassium dihydrogen phosphate (KDP), and deuterated potassium dihydrogen phosphate (KD*P). The damage at the lowest power levels is caused by inclusions. At higher power levels, filamentary damage, which is indicative of self-focusing, is observed in LiNbO3. An analysis of self-focusing data in yttrium aluminum garnet shows that the Kerr effect is the dominant self- focusing mechanism, with some contribution from the thermal effect. Bulk and surface damage thresholds in neodymium-doped thoria:yttrium oxide ceramic are obtained relative to bulk damage thresholds in several optical materials. For solid materials relationships are obtained between the stress-optic coefficients and the electrostrictive coefficients under different geometric boundary conditions.
