At low temperatures a two-threshold behaviour emerges, which has been attributed to the onset of polariton lasing and conventional lasing at the first and the second threshold, respectively. We observe that polariton lasing is stable up to temperatures comparable with the exciton binding energy. At higher temperatures a single threshold displays the direct transition from thermal emission to photon lasing. 2012 New Journal of Physics 14 083014 urn:nbn:de:bvb:20-opus-134022 10.1088/1367-2630/14/8/083014 Physikalisches Institut
