Abstract
Broad area (BA) lasers and amplifiers are robust, compact and highly efficient devices for generation of high power beams. These beams, however, suffer from a poor spatial and temporal beam quality. The stabilization and shaping of the optical beams in BA devices can be achieved, for example, by injection of the optical beam at some angle to the longitudinal axis [1], by the external optical feedback from the corresponding off-axis mirror [2], or by special geometry of the device [3].
