Second harmonic generation - Phase Matching
"Second harmonic generation - Phase Matching" allows you to select the crystal and to calculate all integral parameters: phase-matching angles, phase-matching angular (internal and external) width, phase-matching wavelength width, phase-matching temperature bandwidth, "walk-off" angles, effective nonlinear coefficient, and other.

All results are presented as the functioanal dependencies from the azimuth angle, wavelength, temperature, etc. For each crystal the presentaion of 21 graph dependenies for different phase-matching parameters are possible.

You can calculate the distributions for all the phase-matching widthes.

Also you can calculate the distributions of the efficiency of conversion in the fixed-field-approximation (the absence of decreasing of the fundamental laser radiation).

For effective nonlinearities you can calculate the distributions from initial data and "field" of the effective nonlinearity.
