英文摘要	A compact, light weight laser beam combiner (10;110) includes a pair of concentric annular shells (12;112) defining an annular cavity (14;114) of an annular ring resonator having an annular solid laser gain medium (20;120) disposed therein. The output ends of a plurality of low power and brightness fiber lasers (22;122) are coupled into the cavity (14;114) of the resonator such that fiber laser beams cause the gain medium (20;120) in the resonator cavity to lase and produce an annular beam of laser light. Optical elements (16,18;116,118) of the resonator are operable to feed a first portion of the laser light back through the resonator cavity (14;114) to support regenerative lasing of the laser medium (20;120) and to couple off a second portion of the laser light in the form of a circular beam of high power and high brightness laser light. A fluid may be circulated through the resonator cavity to cool the laser medium.
