Abstract
We describe an optical pumping injection cavity (OPIC) edge-emitting laser which employs GaSb/AlAsSb distributed Bragg reflectors above and below the type-II "W" active region to form an etalon for the pump beam. A pulsed W-O PIC laser emitting at 3.1-3.4 mu m displays an incident threshold pump inte nsity of only 8 kW/cm(2) at 300 K, and incident power conversion efficienci es per facet of 9% at 77 K and 4% at 275 K.
