Abstract

A comparative study of electronic lenses (caused by population change of ground and excited states having different polarizabilities) and thermal lenses induced in Yb:YAG and Nd:YAG rods and disks under lasing and nonlasing conditions is carried out. The transient electronic lens can predominate over the thermal one in the pulsed-pump regime, whereas the stationary thermal lens may be predominant at CW broad pumping. The electronic lens effect is stronger in Yb:YAG than in Nd:YAG crystal.
