Abstract
A laser frequency conversion device employs a dual resonant optical cavity in which closed optical paths exist for both the pump beam and the generated beam. The optical cavity is designed so that the optical paths overlap the acceptance volume in phase space for coupling power from the pump beam into the output beam. At least one of the beams is pumped by an external laser which is aligned and mode matched to the cavity mode. The frequency of the pump laser or the cavity resonance modes is selected, generally by adjustment, to cause buildup of optical power at the pump frequency. The temperature and the angle of the nonlinear material are selected for phase match in the nonlinear interaction within the material. The frequencies of the modes near the output frequency are independently selected to cause buildup of optical power at the output frequency.
