Abstract
The internal conical refraction angles between 0.5321.32 μm, the phase-matching directions of 1.064 μm type I second harmonic generation (SHG) and of 1.32-μm type II SHG are measured in a sphere of CsTiOAsO4 (CTA). The relative sign and absolute magnitude of two independent quadratic nonlinear coefficients are determined by 1.32-μm phase-matched type II SHG conversion efficiency measurements in a sphere and strips: d15=1.09±0.09 pm/V and d24=1.7±0.6 pm/V at 0.65 μm. AH the results are compared with previous work. The comparison of CTA with KTiOPO4 and KTiOAsO4 is made in order to evaluate the crystal which provides the highest conversion efficiency for 1.32-μm type II SHG depending on the crystal length and on the beam waist radius
