Thermo-optical distortion in second-harmonic generation for nonlinear crystals under consideration of the elasto-optical effect

摘要

Thermo-optical distortions are considered with the account of elasto-optical effect at second-harmonic generation (SHG) for crystalline samples, which are in the form of circular cylinders and have a steady-state parabolic temperature field. For crystals ADP, LiNbO$-3$/@, and KDP, the numerical calculations for wave mismatch and efficiency of SHG with account of elasto-optical distortions are carried out.
