Modeling of Thermal Lensing in Nonlinear Optical Crystals

Abstract: An iterative approach to modeling thermal lensing in χ2 frequency conversion processes is described. Careful consideration is given to ensuring consistency of approximations. We find piezo-optic effects can partially compensate the impact of thermal dispersion. ©Optical Society of America OCIS codes: (190.2620) Frequency conversion; (190.4870) Optically induced thermo-optic effects. 1
