36.5 W high-power 976 nm first-order DFB semiconductor diode

High-power 976 nm semiconductor lasers are the core pump sources for ytterbium-doped fiber lasers (YDFLs). This paper reports a 976 nm distributed feedback (DFB) semiconductor laser that achieves an outstanding high-power continuous-wave (CW) output. Based on an epitaxial structu...
