We demonstrate laser emission by photopumping at room temperature from a distributed feedback structure for a surface-emitting laser constructed by alternating growths of a GaAs/AlGaAs multiquantum well and an Al/sub 0.7/Ga/sub 0.3/As layer using molecular-beam epitaxy. A threshold photoexcitation intensity lower than 3.1 x 10/sup 5/ W/cm/sup 2/, a 34-nm longitudinal mode spacing, and a 2.3-nm peak width of the laser emission were observed for the 6-..mu..m-thick multilayer.
