Abstract
A second harmonic laser beam is generated by passing a fundamental frequency laser beam through a single second harmonic generator (SHG) crystal more than two and preferably four times, to increase the amount of power converted from the fundamental beam into the second harmonic beam and to increase the overall efficiency of the conversion.
