Program "SHG - Phase Matching"

      Program "SHG - 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.

	The indices of refraction and the phase-matching directions for all types of interactions.
All possible phase-matching angles versus of the azimuth angle.
	Phase-matching angles versus of the wavelength of fundamental laser radiation.
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.
Phase-matching azimuth angle (XOY plane, NCPM interaction) versus of the fundamental laser radiation wavelength.
You can calculate the distributions for all the phase-matching widthes.
	Phase-matching angular width versus of the fundamental laser radiation wavelength.
Phase-matching temperature width versus of the wavelength of the fundamental laser radiation.
	Phase-matching spectral width versus of the fundamental laser radiation wavelength.
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).
Relation efficiency of conversion versus the angular mismatch.
	Relation efficiency of conversion versus the spectral mismatch.
For effective nonlinearities you can calculate the distributions from initial data and "field" of the effective nonlinearity.
Effective nonlinearity versus wavelength of fundamental laser radiation.
	"Field" of effective nonlinearity versus angles of orientation.
