Abstract

In the scope of the project TRUST, more than 20 aging tests have been performed on about 300 high-power laser diode bars with a variation of the mounting technology, current load, operation temperature, and operation mode. Our main goals were the improvement of the reliability and the determination of acceleration parameters for aging tests. We present selected results of long-time aging tests, acceleration factors, and thermal activation energies for high-power 808 nm laser diodes. Due to the increasing demand for higher output powers, we focus mainly on gold-tin mounted laser bars and show their great potential in comparison to the standard indium packaging technology.
