Abstract

Continuous-wave (cw) nonlinear frequency conversion using quasi-phasematched crystals has become a relatively mature technique for efficiently generating radiation over a broad range of wavelengths. With its high nonlinearity of d_eff ≈ 9.5 pm/V and high damage threshold, PPKTP is an interesting alternative to periodically poled LiNbO₃ and LiTaO₃ (PPLN, PPLT). One important advantage of this material is the absence of photoreffactive effects which, for example, allows operation at room temperature.
