Improved phase locking of laser arrays with nonlinear coupling

Optics 2020-04-08 v1

Abstract

An arrangement based on a degenerate cavity laser for forming an array of non-linearly coupled lasers with an intra-cavity saturable absorber is presented. More than 3030 lasers were spatially phase locked and temporally Q-switched. The arrangement with nonlinear coupling was found to be 2525 times more sensitive to loss differences and converged 55 times faster to the lowest loss phase locked state than with linear coupling, thus providing a unique solution to problems that have several near-degenerate solutions.
