We report a type-II antimonide midinfrared vertical-cavity surface-emitting laser. The emission wavelength of 2.9 &mgr;m is nearly independent of temperature(d&lgr;/dT≈0.07 nm/K)and the multimode linewidth is quite narrow (3.5 nm). The pulsed threshold power at 86 K is as low as 22 mW for a 30 &mgr;m spot. Lasing is observed up toT=280 K,and the peak output power from a 600 &mgr;m spot exceeds 2 W up to 260 K. The differential power conversion efficiency is>1&percent;at 220 K. ©1997 American Institute of Physics.
