  • Third harmonic laser system
    Patent number: 6690692
    Abstract: A third harmonic laser system includes a fundamental wave resonator for generating fundamental laser beam, a second harmonic laser generator for converting fundamental laser beam to a second harmonic laser beam, and a third harmonic laser generator for mixing the second harmonic laser beam with the fundamental laser beam so as to produce a third harmonic laser beam. Multi-pass tripling is used for producing the third harmonic laser beam by means of reflecting and polarizing mirrors, and that the outputted third harmonic laser beam has a high efficiency of about 51% and a high power up to 8.6 W.
