High-power diode lasers for optical recording with operating lifetimes in excess of 10 000 h

Real-time lifetest data are reported which show that single spatial mode CDH-LOC diode lasers can operate stably at 25°C ambient temperature for greater than 10000 h at 40–50 mW output power and 50% duty cycle. This makes CDH-LOC lasers useful for optical disc recording, as well as for a variety of other applications that require high output power in a stable nonastigmatic farfield beam pattern.
