Paper Abstract

We demonstrated high power semiconductor diode lasers emitting around 2.1 μm with the micro-stripe broad area (MSBA) structure which was proposed to improve the broad area (BA) lasers’ lateral beam quality. 1.28W output power at 7A at continuous wave (CW) operation was achieved from the uncoated MSBA laser. It is shown that the micro-stripe structure would lead to worse threshold current and slope efficiency of the lasers because of the less-pumped lossy regions. However, the MSBA lasers would have better heat dissipation system with proper micro-stripe structure and gain advantages on power performance at high currents.
