High power 1.02 mu m single spatial mode laser diodes with low-loss (3.3 cm-1) GaInP buried waveguides have been developed for pumping Pr3+-doped optical fibre amplifiers. A maximum CW light output power of 415 mW and an optical fibre output of 71 mW at 200 mA have been achieved. A preliminary lifetest showed stable operation for over 2300 h under 100 mW CW conditions at 50 degrees C.
