Abstract
Frequency locking of fiber lasers arranged in an array with a nonperiodic order possessing randomly distributed lengths is investigated both theoretically and experimentally. Two coupling methods with different coupling lengths are used to synthesize mode clusters as well as to select and synchronize the sub-supermodes from the mode clusters to form an overall supermode. Frequency locking of 220 lasing elements in an array containing 720 lasers results in a 14-fold increase in the brightness compared with the brightness of an uncoupled laser array. In addition, results are presented describing how to control the far-field distribution of a disordered array.
