Abstract
A frequency converter for converting a single mode input beam at a fundamental frequency to an output beam at a converted frequency is configured with a plurality of spaced optical components defining a resonant cavity. The optical components shape the input beam with at least one beam waist in the cavity. The frequency converter further includes a non-linear crystal located within the cavity in either a divergent beam with a Rayleigh range smaller than a cavity round trip length so that a center of the crystal is spaced from the beam waist along a beam path, or in a collimated beam with a Rayleigh range greater than the cavity round trip length.
