A high quality factor and low loss optical microcavity structure is employed to construct electrically pulse pumped organic laser device. A 4-(dicyanomethylene)-2-i-propyl-6-(1
) film serves as gain layer. IVO and Al films serve as anode and cathode
respectively. The surface-emitting lasing can be observed from the cathode side with the emission peak of 622 nm and threshold current density of 860 mA/cm

. The main key techniques are discussed to realize the laser.
