HIGH-BRIGHTNESS SOLID LASER WITH CONTROLLED SPECTRAL PROPERTIES

摘要

The utility model relates to laser technology. A high-brightness solid-state laser with controlled spectral properties consists of an active element, pumping, self-pumping phase conjugate mirrors, a static Bragg grating in the form of a volume hologram recorded in a 2 mm thick photorefractive lithium niobate crystal with the possibility of rotation of the grating within an angle from 0.405 radians to 0.675 radians relative to the optical axis. The reference mirror is made with the possibility of rotation at a given angle. The technical result consists in providing the possibility of increasing the spectral brightness and tuning the radiation along the wavelength. 1 ill.
