We report a compact green light source consisting of a 1060-nm DBR laser, a periodically poled lithium niobate crystal waveguide and an adaptive optic element consisting of a micro-electro-mechanical system actuator. Up to 350 mW optical power at 530 nm with the wallplug efficiency of up to 15% was demonstrated. The change in the optical power at constant current over the temperature range from 10°C...
An automatic external-cavity laser system for efficient testing of unmounted quantum cascade laser (QCL) bars has been developed. QCLs emitting at 3.45μm and broadband gain media with ∼344 cm1 tunability at 4.4μm have been studied.
We report highly reliable 1060-nm DBR lasers with a single-wavelength output power larger than 350 mW and a failure rate as low as 3.2 kFITs at a heat-sink temperature of 25degC and a gain current of 500 mA. The reliability data of the high-power 1060-nm DBR lasers under longest aging tests at the highest level of current and temperature stress have been obtained for the first time, to the best of...
We report a high kink-free facet power of 852 mW and a high single-wavelength facet power of 350 mW for 1060-nm raised-ridge Fabry-Perot (FP) and distributed-feedback (DFB) lasers, respectively.
