Temperature dependence of angular noncritical phase-matched second-harmonic generation of focused laser radiation

We consider the angular noncritical phase-matched second-harmonic generation characteristics of focused laser radiation, which are revealed in the asymmetry of the dependence of conversion efficiency on crystal temperature. The determining role of vector phase matching in the observed peculiarities...

Summary:We consider the angular noncritical phase-matched second-harmonic generation characteristics of focused laser radiation, which are revealed in the asymmetry of the dependence of conversion efficiency on crystal temperature. The determining role of vector phase matching in the observed peculiarities of the conversion process is shown.
