摘要：
LiNbO3:Fe and LiNbO3:Fe,Me (Me = K, Mg, Zn) crystals are illuminated with frequency-doubled pulses of a e-switched Nd:YAG laser. We detect light-induced absorption changes at high pulse intensities (I > 10(9)Wm(-2)) utilizing cw probe lasers of different wavelengths (lambda(p) = 488, 633, and 785 nm). Intensity dependences as well as relaxation processes after illumination are investigated. Absorption changes increase with increasing light intensity. Strongest effects are observed in reduced crystals. Doping with magnesium or zinc and an increasing lithium content, respectively, diminishes light-induced absorption changes. Our results can be described by a two-center charge transport model.
