WIDE-APERTURE LASER Russian patent published in 2006 - IPC H01S3/00 H01S3/02 

FIELD: quantum electronics, devices for emission and amplification of laser radiation used for action on objects with large areas and volumes.

SUBSTANCE: the laser has a fixed base, body with an active medium in the form of a cylindrical tube, rotator, optical pumping source and a cooling device. At least two optical pumping radiators are positioned inside the active medium. Mirrors of pumping radiation concentration are installed outside relative to the axis of rotation. The resonator mirrors are made cylindrical. The center of the radius of curvature of the resonator mirrors coincides with the axis of rotation of the active medium. The generating lines of the resonator mirrors and the generating lines of the cylindrical surface of the active medium are mutually parallel. Rotation of the body provides circulation of the active medium through the area of emission and effective cooling.

EFFECT: enhanced aperture of laser emission, enhanced efficiency and power, enhanced adaptability to manufacture and service.
