The tuning curves, angular and spectral phase-matching widths are calculated for all possible kinds of OPG in the principal planes of biaxial KTP crystal with Nd:YAG laser pumping at 1.064 µ wavelength. The plots presented enable the maximal nonmonochromaticity and radiation divergence to be found for any value of the signal wave and different interaction types. A particular emphasis has been placed on the OPG investigation under the noncritical phase-matching conditions of the type II along x and y crystallographic axes. The effective nonlinear coefficients as a function of phase-matching angles are calculated in the KTP principal planes.
Key words: nonlinear crystal, laser, phase-matching.
