FIELD: lasers. SUBSTANCE: laser has resonator. There are polarizer and laser element inside the resonator onto optical axis. Laser element is made of activated optical glass made in form of one turn at least. Conductor crosses center of the turn; the conductor is connected to current pulse source. After magnetic field is applied, plane of polarization of laser radiation in fiber turns to (2p-1)90 deg. and crosses polarizer through, as a result gigantic pulse is formed. EFFECT: improved efficiency. 1 dwg
