ABSTRACT:
Third harmonic generated from intra-cavity frequency tripled resonator is disclosed in which a type I or type II phase matching crystal is used as the tripler. Type I phase matching is used for second harmonic generation. The resonator efficiently converts the fundamental laser frequency to its third harmonic laser beam. The laser is highly efficient with high third harmonic output stability. Overall conversion efficiency exceeds 25% and preferably is 50% or higher.
