| Abstract(in English) | A high-power laser diode (>30mW) emitting at around 650nm is indispensable as a light source of a DVD-RAM system. Moreover, high-temperature operation (>～60℃) and high reliability are strongly required. This paper describes some subjects on these requirements and their countermeasures. In addition, a newly developed laser for DVD-RAM is presented. In the development of the laser, we optimized the active layer structure for reduction of the operating current at high-tempemture and applied a window-mirror structure as a mirror hardening technique. As a result, no optical damage up to 150mW and reliable 30-50mW operation at around 60℃ were realized. |
