Lasing action in an electrically pumped organic laser device is demonstrated with a high quality factor (Q) 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)-4H-pyran-doped tris(8-hydroxyquinoline)aluminum (Alq_(3)) film serves as the active layer. A single longitudinal lasing cavity mode is obtained at 621.7 nm with a threshold current density of 860 mA/cm~(2) under a room temperature pulse operation.
