Frequency stabilization and phase locking of laser diodes and laser arrays (FG 87). Progress report
The major accomplishments for FY 86 were: 1. Demonstration of efficient coupling of an injection-locked laser-array single-lobe output into a single-mode optical fiber. A coupling efficiency of 30% was achieved for a 40-element array emitting 500 mW, corresponding to a fiber output power of 150 mW. 2. Demonstration of a novel external ring-laser cavity operation of a gain-guided array. The ring cavity relies on self-injection locking of the array by its own spatially filtered output. As in the case of injection locking, the ring-laser external cavity results in single diffraction-limited-lobe far-field emission of the array, but with the added advantage of eliminating the need for a separate master laser and the associated wavelength and temperature requirements.
