Abstract

We use computer simulation to illustrate how thermally induced phase mismatch affect deep UV harmonic generation. A multicrystal harmonic generator that compensates for thermally include phase mismatch is then presented. We have tested this multicrystal design with a Nd:YAG lasers 4th harmonic generator based on two pieces of (beta) -BaB₂O₄ crystals, and our results demonstrate that it compensates for the thermally include phase mismatch, effectively increasing the interaction length of nonlinear optical crystals during harmonic generation under high loading.
