Abstract:A Yb LMA fiber amplifier based 1030nm laser transmitter capable of operating with high average power and peak power (~500W, 9kW) is presented. The prototype, all-fiber, high TRL level laser transmitter is designed to meet all the single aperture requirements of a multi aperture deep space laser beacon system including operation with Nested pulse position modulation (PPM) format. Nested PPM format consist of an inner modulation PPM-(8,4) with 128nsec slot size and an outer modulation PPM-(2, 2) 65.5usec slot si… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
