Recently electrical injected visible vertical surface emitting lasers (VCSELs) have been reported with a pulsed threshold current of about 30 mA. In this paper we report for the first time the continuous wave (cw) operation of such visible VCSEL diodes. In conclusion we have fabricated visible gain-guided surface emitting laser incorporating In0.5GA0.5P/ In0.5Al0.35Ga0.15P quantum wells Al0.5Ga0.5As /AlAs DBRS. Cw operation was achieved for temperature up to -25 C with a low threshold current of 4.6 mA. Fine adjustment on layer thickness and optimization in the proton implantation steps may yield room temperature continuous operation.
