Abstract
We report on the high-temperature performance of high-power GalnNAs broad area laser diodes with different waveguide designs emitting in the 1220-1240-nm wavelength range. Large optical cavity laser structures enable a maximum continuous-wave output power of >8.9 W at T = 20degC with emission at 1220 nm and are characterized by low internal losses of 0.5 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> compared to 2.9 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> for the conventional waveguide structures. High-power operation up to temperatures of 120deg C is observed with output powers of >4 W at T = 90degC. This laser diode showed characteristic temperatures of T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</sub> = 112 K and T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> = 378 K.
