Abstract
Disclosure is made of a laser system comprising a non-linear crystal that converts light at a fundamental wavelength to light at a harmonic wavelength and that has a thickness such that there is a phase mismatch between light at the fundamental wavelength and light at the harmonic wavelength in said crystal; first means for forming one of a travelling wave optical cavity and a standing wave optical cavity at the fundamental wavelength; and second means for forming one of a travelling wave and a standing wave optical cavity at the harmonic wavelength, the first means and said second means are located relative to the faces of said crystal such that the total phase mismatch of the light at the fundamental wavelength and the light at the harmonic wavelength, in the round trip path through the crystal and between each face of the crystal and the first means and the second means, is equal to an integral multiple of 2.pi..
