The effect of light from the different region of spectrum (from the intrinsic and impurity absorption region of spectrum) on the mobility of charges in pure and alloyed by gadolinium atoms crystals of p-GaSe have been investigated at temperature of 77-350 K. It is established that the value and course of dependence of mobility on the temperature changes at influence of light. In addition there is residue mobility effect. All this effect of light on the mobility depends both on the dark resistivity of pure and on the doping level and on the spectrum composition of light. It is found out that observed effect of he light on the mobility in both group of crystals due to the optical smooching of potential barrier free energetically zone.
