Abstract
We report on a record-high output power from an optically pumped quantum-dot vertical-external-cavity surface-emitting laser, optimized for high-power emission at 1040 nm. A maximum continuous-wave output power of 8.41 W is obtained at a heat sink temperature of 1.5 degrees C. By inserting a birefringent filter inside the laser cavity, a wavelength tuning over a range of 45 nm is achieved.
