DURIP-94: Phase Conjugate Injection Locking of Laser Diode Arrays.
Abstract
This is an 'equipment only' grant under the Defense University Research Instrumentation Program. A report of the results obtained with this equipment is contained in the final report for Grant F49620-95-1-0082, 'Phase-Conjugate Injection Locking of Laser Diode Arrays.' To avoid duplication of paperwork, only a partial summary of that report will be duplicated here. This grant is to produce high-brightness, narrow-frequency light beams from semiconductor laser arrays using optical phase conjugation. The investigators recently demonstrated that their proposed techniques are both practical and efficient, and can be applied to commercially available semiconductor lasers. Their experiments coupled an optical phase conjugator to a broad-area semiconductor laser, causing the laser to emit a 0.5 watt, near-diffraction-limited output beam. Their system is simple and compact, and it also automatically adjusts for any frequency drift or gradual misalignment of the optical components. The investigators extended their techniques from single, broad-area lasers to powerful semiconductor laser arrays.
