Abstract:

We report on experimental and theoretical study of temperature tuning of single pass quasiphase- matched second harmonic generation in a plane parallel PPMgOLN (periodically poled MgO doped LiNbO3) crystal in a green microchip laser. Periodic oscillations of second harmonic power upon variation of the temperature are observed. The oscillation period (4.8°C – 8.4°C) is several times smaller than the temperature acceptance bandwidth (18.4°C – 32.1°C), and the period strongly correlates with the crystal length. Formula for temperature dependence of second harmonic power is derived, which takes into account multiple reflections of fundamental and second harmonic waves in the nonlinear crystal. Comparison of experimental and theoretical data allows us to conclude that the origin of the oscillations is the multiple beam Fabry-Perot interference in the plane parallel nonlinear crystal.
