Abstract

Engineering Engineering, Electrical & Electronic Optics Physical Sciences Physics Physics, Applied Science & Technology Technology
In this letter, we report on a high-power operation of an optically pumped quantum-dot semiconductor disk laser designed for emission at 1180 nm. As a consequence of the optimization of the operation conditions, a record-high continuous-wave output power exceeding 7 W is obtained for this wavelength at a heat-sink temperature of 2 degrees C. A wavelength tuning over a range of 37 nm is achieved using a birefringent filter inside the cavity.
