摘要：

We report an edge-emitting mid-infrared (IR) (lambda = 3.3-3.7 mu m) "W" laser incorporating an optical-pumping injection cavity (OPIC), The active region of the W-OPIC is sandwiched between two Bragg mirrors that significantly enhance the pump-beam absorptance at lambda(pump) = 2.098 mu m. Pulsed experiments demonstrate that besides suppressing the threshold pump intensity, this design enhances the differential power conversion efficiency (e.g., 7.1% per uncoated facet at 220 K) and lowers the internal loss (e.g., 20 cm(-1) at 240 K) compared with all previous optically pumped mid-IR lasers.
