FIELD: laser equipment. SUBSTANCE: laser includes dispersion element 1, active medium 2, mirror 3, optical system 4 and pumping device 5. Optical system is fabricated in the form of multisided prism. Resonator of laser formed with mirror 3 and enticollimation element 1 in combination with multisided prism creates feedback for beams of different lengths in different sections of active medium which provides for formation of radiation in the form of specified set of lengths of waves. EFFECT: enlarged set of ranges of waves of simultaneous generation in wide region of spectrum. 1 dwg
