External quantum efficiency of > 20 percent has been achieved from tunable CW InSb lasers resonantly pumped with a CO laser. Thin InSb platelets at-1linewidth, mechanically or thermally tunable over several cm-1. Magnetic-field effects on the threshold and emission frequency have also been studied.
