A Multi-fiber Laser Using a Phase-locking Talbot Self-imaging Effect

摘要

An all fiber based compact phase-locking fiber laser design is proposed by using a Talbot mirror fiber device (TMFD). We numerically demonstrate that periodically placed fibers lasers can be phased together using a large mode area (LMA) fiber element. The LMA fiber with a partial reflector at one end acts as a Talbot mirror, when the input beam to the LMA fiber travels one round trip in the LMA, it will self image back at the fibers' input.
