Reduction in the operating current of high-power 660-nm AlGaInP laser diodes with an AlInP current blocking layer

Abstract

Summary form only given. High-power 660-nm AlGaInP laser diodes with a stable transverse mode are indispensable as the light source of recordable or rewritable DVD systems. The window-mirror structure is effective for obtaining a high COD (catastrophic optical damage) level. We report on high-power 660 nm AlGaInP laser diodes with Zn-diffused window-mirrors and an AlInP current blocking layer. These laser diodes have demonstrated stable operation with the highest light output power to our knowledge of 80 mW for the real index guide structure.
