890 nm大功率半导体激光泵浦源性能优化
Performance Optimization of High-power 890 nm Semiconductor Laser Pump Sources
摘要
Abstract
High-power semiconductor lasers,as core pumping sources for solid-state and fiber laser systems,are of sig-nificant application value in the fields such as industrial processing and national defense.This paper reports on a pump la-ser developed to meet the requirements of mid-infrared fiber laser systems.As a pump source for fiber lasers,the device must possess high output power and high efficiency.By optimizing quantum well materials,waveguide structures,and doping profiles,a single-emitter laser with a 200 µm stripe width was fabricated,achieving an output power of 16.12 W and a maximum conversion efficiency of 53%.Through beam combining and coupling modules,the laser was coupled into a 105 µm optical fiber with a numerical aperture(NA)of 0.18,delivering a maximum output power of 113 W.Test re-sults indicate that the laser exhibits excellent power and temperature stability,thereby enhancing its reliability.关键词
