A multicrystal harmonic generator that compensates for thermally induced phase mismatch

Abstract

A multicrystal means of compensating for the thermally induced phase mismatch encountered in the generation of high average power UV radiation is described. The concept is experimentally tested with a Nd:YAG laser 4th harmonic generator based on two β-BaB_2O_4 (BBO) crystals. Single versus two crystal results demonstrate that this design compensates for the thermally induced phase mismatch, effectively increasing the interaction length of nonlinear optical crystals during harmonic generation under high loading.
