Abstract
An apparatus and method for nonlinear conversion of laser light is described herein. The apparatus of the instant invention comprises a fiber coupled light source, a cavity in optical alignment with the first light beam from the light source, wherein the cavity comprises: two concave mirrors, one or more Brewster-cut periodically poled crystals, and a cavity servo to lock the length of cavity to laser frequency. In one aspect of the present invention the feedback to the lock is S-polarized component of first laser light reflected off the Brewster surface of nonlinear crystal.
