FIELD: laser equipment. SUBSTANCE: resonator of laser formed with flat resonator mirror and dispersion element in conjunction with focusing lens forms feedback for beams of different lengths of waves in different sections of active medium which provides for expansion of generation spectrum and for formation of radiation of specified spectrum composition in combination with preset lateral distribution of density of pumping power in active medium. EFFECT: expanded radiation spectrum.
