MULTICHANNEL COHERENT OPTICAL RADIATION SOURCE Russian patent published in 1996 - IPC

FIELD: laser technology. SUBSTANCE: lasers 1 are disposed periodically along the arc of the circle about semitransparent communication mirror 2, which is made in form of annular cylinder. Lasers are mounted at the plane being perpendicular to axis of symmetry of mirror, and oriented radically in relation to the axis. Radius of mirror and distance from apertures of lasers to axis of the mirror satisfies to the relation got on the base of diffraction theory from the condition of complete representation of periodical field of laser set for Talbo cylindrical resonator. The relation given in the description s the following: $$$, where r is radius of the mirror, R is distance from apertures of lasers to axis of the mirror, $$$ is angle between axes of adjacent lasers, $$$ is generation wavelength. EFFECT: improved efficiency of operation. 2 dwg
