abstract

Multilayer coatings, such as Antireflection (AR) & High Reflection (HR), are used respectively in front & back facet coatings of diode laser for high power and long life operation. In this paper, we coated single layer AR coating using Al2O3MgF2 and multilayer HR coating using Al2O3 and MgF2 as a low refractive index layer and Si as high refractive index layer on GaAs substrates for optimization of coating conditions and HR coating using Al2O3\Si and MgF2\Si on diode laser chips. AR coating of diode laser is planned.
