Abstract
A forming optical contortion in a crystal undoped lithium niobate at transmitted laser emission researched by the method of monitoring of second harmonic generation kinetics. The basic changing of refraction index is combined with a transport charge processes for the phase matched second harmonic generation, and with a local recharge effects of photorefractive centers for the phase mismatched generation. The external magnetic field changes a photorefractive sensitivity of a crysatl. They are compensated photorefractive sensitivity up to 0 in the magnetic induced field -0.38 T. The influence of a magnetic field is concerned with changing conditions of an electrons photoexcitation.
