Paper Abstract

We developed several ten sorts of harmonic mirrors, anti- reflector and separator coatings for cavity components, lens, separators to satisfy the needs of YAG harmonic laser system. This paper mainly introduced the optical properties and the damage thresholds of some of these coatings. At a normal or a 45 degree incidence angle, the separators satisfied the requirements such as HR for 1 (omega) , 2 (omega) /HT for 3 (omega) , or HR for 2(omega) /HT for 1 (omega) , 2(omega) , or HR for 2 (omega) , 4(omega) , and the mirrors or anti-reflectors could be simultaneously used for two or three wavelengths among the base wavelength 1053nm and its second, third, fourth harmonic wavelength.
