Temperature Dependences of Laser-Induced Damage Resistance for Dielectric Materials

Abstract

We evaluated the laser-induced damage resistance of dielectric coatings at temperature from 123 K to 473 K with 1064-nm wavelength at 4-ns pulse duration. In the results, laser-induced damage resistances were improved at low temperature for dielectric coatings (single layer of SiO₂ and MgF₂). These results are important for understanding the laser-induced damage mechanisms.
