Abstract
Lasing action in an electrically pumped organic laser device is demonstrated with a high quality factor microcavity structure formed by two high-reflective and low-loss electrical contacts. A 4-(dicyanomethylene)-2-i-propyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)--pyran-doped tris(8-hydroxy- quinoline)aluminum film serves as the active layer. A single longitudinal lasing cavity mode is obtained at with a threshold current density of under a room temperature pulse operation.
