1. A fiber optic laser array, comprising:
- a plurality of fiber optics, wherein each fiber optic of said plurality of fiber optics comprises an active laser gain medium;
means for controlling the length of said each fiber optic;
means for optically pumping said active laser gain medium of said each fiber optic to produce a plurality of laser beams; and
means for phase locking said plurality of laser beams.

Abstract
Architectures for coherently combining an array of fiber-based lasers are provided. By matching their lengths to within a few integer multiples of a wavelength, the spatial and temporal properties of a single large laser are replicated, while extending the average or peak pulsed power limit.
