Waveguide laser formed in YAG:Nd~(3+) crystal by femtosecond laser inscription

摘要

A technique of direct writing of depressed cladding waveguides by a tightly focused, femtosecond laser beam in laser crystals has been developed. A laser based on a depressed cladding waveguide in a Neodimium doped YAG crystal has been demonstrated for the first time.
