Abstract
With optical pumping, a lead salt vertical-cavity surface-emitting laser ha s been operated at wavelengths in the 4.50-4.60 mu m range at temperatures up to T = 289 K. For a 60 mu m x 90 mu m pump spot, a device with a PbSe ac tive region and Pb1-xSrxSe/BaF2 quarter-wave mirror stacks was realised whi ch had an unsaturated peak output power of 38mW at 249K.
