摘要: Based on a multi-three-wave interaction model, we theoretically analyze the intense amplification competition between fanning noise and signal beam in doped lithium niobate crystals. Our results show that can be most effectively amplified for specific value of photovoltaic field because beam. When threshold effect incident-light intensity photorefractive light-induced scattering is taken into account LiNbO3:Fe, M(M=Mg2+, Zn2+, In3+, Sc3+) crystals, pump intensity.
