Second harmonic generation - Plane wave conversion - Thermo

      "Second harmonic generation - Plane wave conversion - Thermo" allows you to computate the influence of a thermic processes (self-interaction and inhomogeneous cooling) at a second harmonic generation of a modulated plane waves (hyper-Gaussian beams). The computations are executed with taking into account the dispersion of a linear and two-photon absorptions, nonlinear coefficients and etc.



Program is based on Working Datbase of a Crystal's Parameters

      There are three steps of a computations - energy parameters computation, computation of a temperature fields and violation of a phase-matching conditions.



The integral parameters and dependencies are calculated
