Abstract
Fischer and Ohmer [J. Appl. Phys. 81, 425 (1997); 77, 5942 (1995)] could no t explain the paradox concerning the anomalously low phase matching angle f or second harmonic generation of CO2 laser radiation in ZnGeP2 crystal by t heir measured birefringence and its temperature dependence. Based on their measured birefringence and its temperature dispersion we have shown that a temperature rise of such crystal by 150 degrees C or so, is enough to expla in this anomaly.
