Abstract :
With optical pumping, a lead salt vertical-cavity surface-emitting laser has been operated at wavelengths in the 4.50-4.60 mm range at temperatures up to T=289 K. For a 60 μm×90 μm pump spot, a device with a PbSe active region and Pb1-xSrxSe/BaF2 quarter-wave mirror stacks was realised which had an unsaturated peak output power of 38 mW at 249 K
