Abstract
Ridge waveguide quantum well (QW) diode lasers in the green/blue regio n have been operated at voltages as low as 7 V in ZnCdSe/ZnSSe/ZnMgSSe pseudomorphic separate confinement heterostructures. These lasers inc lude a p-Zn(Se,Te) graded gap ohmic contact layer to the top metal ele ctrode. Without any attempt at heatsinking, and without reflective fac et coatings, these devices have operated at pulsed duty cycles of 20% at room temperature, with average power output of several milliwatts.
