Paper Abstract

This paper presents experimental results on nonlinear refraction, nonlinear absorption and optical limiting in photrefractive crystals Bi12SiO20 (BSO) and Bi12GeO20 (BGO) at the fundamental and second harmonic wavelengths of picosecond Nd:YAG laser radiation. It is shown that nonlinear refraction was due self-focusing process when nonlinear absorption was due to three-photon absorption at the wavelength of 1064 nm and two-photon absorption at the wavelength of 532 nm.
