Abstract
CsB/sub 3/O/sub 5/ has been found to be phase matchable for SFG down to 0.185 /spl mu/m by mixing the fifth harmonic of a Nd:YAG laser at 1.0642 /spl mu/m and the output of a KTP parametric oscillator pumped by the second harmonic of the same Nd:YAG laser at 20.0/spl deg/C. Improved Sellmeier's equations and nonlinear optical constant of this crystal are reported. >
