FIELD: physics.
SUBSTANCE: invention relates to laser equipment. Tunable laser resonator, which is made according to the Fabry-Perot resonator scheme, has an active medium, a volume reflecting hologram with flat isophase surfaces parallel to the surface of the hologram fixed on a rotary device whose rotation axis lies in the plane of the hologram. On the path of the light reflected by the hologram a flat mirror is installed at angle of 90° to the hologram surface, and on the path of the light beam reflected by said mirror, an end reflector is installed.
EFFECT: technical result is enabling design simplification.
