Program "SHG-MPW-Heat"

   Main applications

         Program "SHG-MPW-Heat" 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.

   Examples (click on picture for detail information)

Program is based on Working Data Base 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.
The adiabatic and average temperature "fields" are computated.
The computated results can be presented as 3D-graph.
The violation of a phase-matching conditions for the laser beam is calculated.
Program allows you to select the optimal tuning of crystal's orientation angles or pumping wavelength for maximization of frequency conversion.
