Abstract

A fiber laser with 180 GHz ultrabroad linewidth is developed using a broadband light source and a bandpass filter. Active phase locking of two fiber amplifiers with 180 GHz linewidth is successfully realized using stochastic parallel gradient descent technique. The fringe contrast of the interference pattern is as high as 65% when active phase control is implemented. The reported results indicate a promising power scalability of fiber amplifier modules developed for phase locking.
