Above-room-temperature operation of vertical-cavity surface-emitting lasers emitting in the mid-infrared is reported. The stimulated emission is generated in PbTe quantum wells embedded in two-wavelength microcavities by optically pumping with fs laser pulses. The spectrum of the laser modes is broadened and blue-shifted due to dynamic band filling. The intensity of the mid-infrared emission and the laser threshold depends on the energy of the microcavity resonance. At a wavelength of 3.1 μm, laser operation is obtained up to a temperature of 65 °C, limited by nonradiative recombination processes. © 2001 American Institute of Physics.
