Abstract
A monolithic crystalline material for quasi-phase-matching is described. The material includes a plurality of wafers of an odd multiple of coherence length thickness, having their faces bonded together by diffusion bonding. The wafers are oriented relative to one another to alternate their signs of nonlinear susceptibility. The invention also includes a method for producing optical radiation of a selected frequency by quasi-phase-matching, several specific methods and materials based on the discovery responsible for the invention, a generator for radiation of 60 THZ frequency of significant power, and a method of fabricating the material.
