We report multi-watt, TEM00 emission from a 2 mum Sb-based optically-pumped semiconductor disk laser utilising an intra-cavity diamond heat spreader for thermal management. An output power of 5 W and a wide tunability of over 160 nm are achieved.
Pump power scaling with spot size is studied experimentally and theoretically in a 1060 nm VECSEL with a diamond heatspreader. The dependence of the efficiency and thermal roll-over on pump spot size are discussed.
We report the first high-power vertical external-cavity surface-emitting laser operating at 1.3 /spl mu/m. Continuous-wave output power greater than 0.6 W was achieved using a GaInNAs/GaAs structure capillary-bonded to a single-crystal diamond heatspreader.
