Computational solution of the heat diffusion equation for Pulsed Gaussian Second Harmonic Generation (SHG), where heat generation results from nonlinear absorption in the crystal.

Open-source Fortran toolkit for simulating pulsed Gaussian second harmonic generation (SHG) in KTP crystal. Investigates efficiency changes with pulse energy, laser spot size, and cooling temperature using coupled field-phase-heat equations with thermal effects and phase mismatch analysis.

Computational model of Phase Mismatch in Pulsed Gaussian Second Harmonic Generation (SHG), where the mismatch arises from heat absorbed in the nonlinear crystal. The heat source is the SHG process itself.

Computational model of Depleted Pulsed Gaussian Second Harmonic Generation (SHG) in Type II configuration, where the interaction occurs between fundamental beams with orthogonal polarizations (ordinary and extraordinary) in KTP crystal. The model assumes ideal conditions and neglects thermal absorption effects.

Heat-coupled depleted pulsed Type II SHG model in KTP crystal. Solves 5 coupled differential equations (3 field, 1 heat with temp-dependent conductivity, 1 phase) using FDM for thermal phase mismatch and lensing.
