AB - We suggest a new way to compensate for the thermal lensing effect in the mid-power solid-state lasers. This can be done by the use of a liquid-crystal adaptive lens with optically controlled focal length (optically addressed lens -- OAL) which is a modification of the modal liquid crystal lens (MLCL) which has recently been suggested and successfully implemented. The phase shift introduced by OAL into the transmitted light wave is theoretically shown to correspond to a converging lens whose focal length depends on the light intensity distribution across the aperture. OAL implements an intra-cavity optical feedback, which can effectively compensate for the laser beam defocus resulted from the emerging thermal lensing. For various types of resonators the beam stability is improved by the use of OAL. Correction becomes more effective if the OAL is positioned close to the laser rod.
