Abstract

Antimony laser diodes emitting at 2 μm have shown great potential due to the extraordinary performance in gas detecting and other promising fields. However, it is difficult to increase the power of antimony laser diodes, the applications of which would be restricted greatly. In this paper, we report the watt-level antimony laser diodes emitting at 2 μm developed by our group, and the maximum output power can achieve about 1.082W at 20℃ with the injection current set as 5A, showing excellent performance.
