Abstract
A specially cut uncoated birefringent crystal having three Brewster-cut faces with adjacent coated Brewster-cut coupling prisms are used for optical frequency conversion. Two input frequencies are used to obtain a third frequency by sum-frequency generation. The uncoated birefringent crystal permits high power input beams.
