High-power CW operation of 780 nm T3 laser diodes

Stable laser operation at over 100 mW in the wavelength range of 780nm has been achieved by the T3 structure. The CW light output power at room temperature was over 160mW. The narrow beam divergence of low ellipticity has been realised. The lasers have been in operation for more than 800h at 40mW at 60°C with no significant degradation.
