Paper Abstract

We report on laser diode bars with wavelengths ranging from 793 to 1080 nm and optimized for high power and high temperature operation. For 808 nm bars output power values of 300 W at 300 A drive current and 200 μs pulse length have been recorded at a cooler temperature of 75°C. Extending our wavelength range to 1080nm we report on bars with >65% power conversion efficiency in CW operation and more than 500 W output power for a wide range of qCW modes. Finally, the properties of a 6-bar stack with 3 kW output power at 460 A drive current and 200 μs pulse width will be discussed.
