Abstract
The invention utilizes a laser cavity between two spherical mirrors, between which an oscillation wave propagates. An amplifying medium and an interaction medium are located on the path of the oscillation wave. A signal wave interferes with the oscillation wave in the interaction medium. A modulator of said wave makes it possible to initialize the process to obtain an output beam emerging in the desired direction.
