摘要

Cascade pumping schemes that utilize single-QW gain stages enhanced both the power conversion efficiency and the output power level of GaSb-based diode lasers that emit near and above 3 μm at room temperature. The cascade lasers discussed in this work had densely stacked type-Ⅰ QWs gain stages characterized by high differential gain. The 3 μm emitting devices demonstrated CW threshold current densities near 100 A/cm~2, a twofold improvement over the previous world record, that resulted in peak power conversion efficiencies increasing to 16% at 17℃. Comparable narrow ridge two-stage devices generated more than 100 mW of CW power with ～10% power conversion efficiencies. Three-stage multimode cascade lasers emitted 960 mW of CW output power near 3 μm and 120 mW CW near 3.3 μm.
