Abstract
Laser type source of coherent luminous radiation including a resonant cavity, an amplification medium placed in the resonant cavity and a dynamic photosensitive material which is placed in the resonant cavity to form a self-adapting spectral and/or spatial filter, characterized in that the cavity is a ring laser cavity and in that the dynamic photosensitive material is placed at the intersection of two beams.
