Efficiency optimization of high-power GaAs lasers by balancing confinement and threshold

A. Boni, P. Della Casa, D. Martin and P. Crump

Published in:

27th International Semiconductor Laser Conference (ISLC), Potsdam, Germany, Oct. 10-14, ISBN 978-1-6654-4133-9, TuP2.3 (2021).


Studies balancing modal gain (confinement) and facet reflectivity in high power 940 nm lasers using extreme-triple-asymmetric epitaxial designs enable > 70% efficiency at 12 W output and low temperature sensitivity. Insight into carrier losses that limit device performance are discussed.
