Paper Abstract

The effective nonlinear coefficients, tuning curves, angular and spectral phase-matching widths are calculated for all possible types of optical parametric generation in the principal planes of biaxial KTP crystal at Nd:YAG ((lambda) p equals 1.064 micrometers ) laser pumping. The plots presented enable the maximal nonmonochromaticity and radiation divergence to be found for any value of the signal wave and different interaction types. We developed a numerical simulation of nonstationary optical parametric generation by solving the cut-off system of coupled equations, which describes the three wave interaction in oscillator cavity, partially filled with KTP crystal. The dependencies obtained demonstrate the dynamics of signal pulse generation development. The optimal crystal and resonator parameters were found to ensure the maximal optical parametric oscillator efficiency.
