DISK LASER WITH MODULATED RESONATOR REACTANCE FACTOR (VERSIONS) Russian patent published in 2009 - IPC H01S3/06 H01S3/08 

FIELD: physics; optics.

SUBSTANCE: invention concerns laser radiation sources. The disk laser contains an optically connected active component, resonator, resonator Q-switch, a source of pumping of an active component and cooling system. Thus the active component is executed in the form of a spherical disk or a thin flat disk; the source of pumping executed in the form of a matrix of laser diodes, is allocated on an external surface of an active component; the Q-switch is executed in the form of the passive or active Q-switch, thus the modulator and an active component form the uniform block; mirrors of the basic resonator are applied on an external surface of an active component and an external surface of the modulator; the arrangement is in addition supplied by the flat half-transmitting mirror forming the additional resonator with a highly-reflecting mirror of the basic resonator. The arrangement can be additionally supplied by a lens mounted in the additional resonator, or the Q-switch with the lateral radiation coupling allocated in the additional semiconcentric resonator, thus the flat mirror has 100% reflexion on laser radiation wave length.

EFFECT: creation of the disk laser with several nanoseconds and less pulse duration.
