Reliable high-power 1060nm DBR lasers for second-harmonic generation

Highly reliable 1060 nm DBR lasers are reported with a single-wavelength output power greater than 350 mW and a failure rate as low as 1.7 kFITs, at a heatsink temperature of 25 C and a gain current of 500 mA. The green-light power of up to 184 mW has been generated by frequency doubling of these DBR lasers.
