Abstract

The data on change of phase synchronism conditions at the second harmonic generation in the KD*P crystals are presented for the first time. This changes are due to the influence of arising at additional irradiation of the sample photorefraction. The calculation on the basis of the phenomenological model was compared to the experimental data and has revealed their basic divergence. Direct measurements of the induced by the photorefraction internal field in the sample are made for the first time. The definite photorefractive efficiency (up to 0,5 kV/nm of the internal electrical field at the energy of pulse irradiation are 1 - 2 tens J/nm²) point to necessity of the account it in the majority of situations, when the nonlinear-optical effects are excited.
