Abstract
The operating fluence of traditional zigzag slab laser amplifier is limited by the interfacial laser damage between the laser crystal and SiO2 film at the total internal reflection surface. A novel coating solution for the total internal reflection surface was proposed to increase the laser damage resistance. A HfO2 layer with optimal thickness was inserted between the laser crystal and SiO2 film to manipulate electric-field intensity at the vulnerable crystal-film interface to be zero. The laser damage resistance of this new coating for the total internal reflection surface is about two times higher than that of traditional zigzag slab laser amplifier.
