Abstract

We designed and fabricated a double-core-slab-waveguide semiconductor laser for end optical pumping, and demonstrated its laser operations. We developed a method of characterization and analysis to evaluate the pumping profile and efficiency, and showed that 10% of the input power entered through a facet edge was used for uniform pumping over the 500 m cavity and 9% for local pumping within 40 m near the edge.
