In high-power laser system, hot image can be intense enough to damage expensive optical components, and hinder the safe operation of the laser system. Previous study of hot image effect has been concentrated on the case of the light beam normally incident on the nonlinear medium slab. However, the nonlinear medium slab in the realistic disk amplifier is tilted with respect to the propagation axis. An experimental study of hot image effect in an intense laser beam through a tilted nonlinear medium slab is presented. It is shown that, relative to the case of laser beam normally incident on the n...
