Abstract
Direct experimental evidence for excitonic lasing is obtained in optically pumped V-groove quantum wire structures. We demonstrate that laser emission at a temperature of 10 K arises from a population inversion of localized excitons within the inhomogeneously broadened luminescence line. At the lasing threshold, we estimate a maximum exciton density of about
