Abstract We demonstrated experimentally the dependence of two-beam coupling on the incident pump intensity in our samples of doped LiNbO₃ crystals. Our results show that there is an optimum pump intensity for the signal beam amplification, which can be easily controlled by doping the LiNbO₃ crystal with suitable concentrations of Fe and damage-resistant dopants such as Mg, In, and Zn.
