Abstract
Abstract A compact laser amplifier system in which a plurality of facepumped annular disks, aligned along a common axis, independently radially amplify a stimulating light pulse. Partially reflective or lasing means, coaxially positioned at the center of each annular disk, radially deflects a stimulating light directed down the common axis uniformly into each disk for amplification, such that the light is amplified by the disks in a parallel manner. Circumferential reflecting means coaxially disposed around each disk directs amplified light emission, either toward a common point or in a common direction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
213 words
A compact laser amplifier system comprising: a plurality of spaced face-pumped disk means of lasing material aligned along an axis of symmetry, a plurality of flashlamp means positioned adjacent each face of each of said disk means, reflective housing means positioned around said disk means and said flashlamp means and provided with a central opening and a plurality of peripheral openings adjacent said disk means, said plurality of disk means each being provided with a central aperture therethrough, a partially reflective cone-shaped member positioned in each of said central aperture of each of said disk means, laser oscillator means positioned to direct a stimulating light pulse along said axis of symmetry, through said central opening in said housing means and through said central apertures of said disk means whereby said partially reflective cone-shaped members each deflect a portion of the light pulse radially and uniformly into each of said disk means wherein each portion of said light pulse is amplified as it passes radially outwardly through said disk means, circumferential mirror means positioned about said housing means for directing the amplified light emissions from said disk means in parallel beams coaxial with said axis of symmetry, and reflector means positioned to intercept said annular beams and direct same to a common focal point.
