Paper Abstract

Spherical and cylindrical lenses with intensity dependent focal length are investigated experimentally. The lenses were photosensitive enough for incident laser power about 0.5 mW/cm2. Two adaptive systems are implemented to demonstrate feasibility of a) power-in-diaphragm stabilization and b) auto-correction of defocus, in all-optical setups. With very little efforts on optimization, the first system reduced intensity variation of 150% down to less than 5%, and the second one practically removed the optical power variation in the output beam when of the input beam optical power increased up to 0.46 dptr.
