Multilayer antireflection coatings for solid state lasers

摘要: A solid state laser is provided on at least one mirror surface with an antireflection coating comprising two contiguous layers, of which has a refractive index greater than, and the other less square root active region laser. The AR impedance matched to by proper choice thicknesses layers. In preferred embodiment for AlGaAs double heterostructure junction comprises innermost layer ZnS outermost Al2O3.
