Abstract

We study type II 1.32 μm second harmonic generation (SHG) in a RbTiOAsO4 optically contacted walk-off compensated device. The reduction of the effective walk-off angle by a factor of 3.7 with respect to KTiOPO4 for the same interaction leads to an enhancement by a factor of 10 of the conversion efficiency. A model is proposed for both type I and type II SHG in such a structure. The angular tuning curve is a multi-peaked one, as predicted by the model. The enhancement of the SHG conversion efficiency allows us to optimize the generation of blue laser light at 440 nm: a specially designed KTiOP0.98As0.02O4 solid solution crystal achieves angular non-critical phase matching at room temperature for type II sum frequency generation 1.32 μm+0.66 μm →0.44 μm.
