Abstract

High-power 660-nm AlGalnP laser diodes with a stable transverse mode are indispensable as light sources for recordable or rewritable DVD systems. High-speed recording is strongly required in these systems. The laser beam intensity focused on the optical disc must be increased to meet this requirement. A small aspect ratio for the beam divergence as well as high-power operation of 660-nm laser diodes is indispensable in order to achieve this.
