Very short period (AlGaAs)/sub m-italic/(GaAs)/sub n-italic/ superlattices (SL's) have been used for single quantum wells (SQW's) of visible laser diodes emitting in the wavelength region of 680--785 nm for the first time. The threshold current of graded-index separate-confinement-heterostructure (GRIN SCH) lasers with SL SQW's is lower than that of lasers with AlGaAs alloy SQW's. The ridge-waveguide structure GRIN SCH SL SQW laser emitting at 785 nm shows the low threshold current of 11 mA.
