Abstract

High power diode lasers have demonstrated reliable output power of more than 50W per diode far beyond 10,000 hours. Record output power of more than 300W per diode laser bar has been reported. The improved reliability of the semiconductor material demands a review of the performance of the actively water cooled heatsink with regards to the expected lifetime. Results from corrosion tests at various water conditions for durations of more than 13,000 hours predict an extended usage of water-cooled heatsink beyond 20,000 hours without significant performance change.
