An arrangement based on a degenerate cavity laser for forming an array of nonlinearly coupled lasers with an intracavity saturable absorber is presented. More than 30 lasers were spatially phase locked and temporally Q switched. The arrangement with nonlinear coupling was found to be 25 times more sensitive to loss differences and converged five 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.

具有非线性耦合的改进的激光阵列锁相。

提出了一种基于简并腔激光器的装置，用于形成具有腔内可饱和吸收器的非线性耦合激光器的阵列。超过30台激光器在空间上被锁相并在时间上进行了Q转换。发现与线性耦合相比，具有非线性耦合的布置对损耗差异的敏感度高25倍，并且收敛到最低损耗锁相状态的速度比线性耦合要快五倍，从而为具有多个近似退化解决方案的问题提供了独特的解决方案。
