The authors demonstrate up to 4.35 W output power from a Stranski-Krastanow grown quantum dot semiconductor disk laser (SK-QD SDL), representing a 15 times increase in power from the previous published maximum power in the work of Germann et al. (2008), and the first multi-Watt output from any QD SDL. The experimental demonstration of a multi-Watt power level continuous wave operation of QD based...
In this paper, we report for the first time to our knowledge a diode pumped cone-refringent Nd:KGW laser in a simple two mirror cavity configuration that produces constant output power and excellent beam quality independent of cavity length even at the edge of stability. We present a simple cavity design rule that predicts the maximum cavity length that is stable for the operation of this laser and...
We present ultra-efficient conical refraction Nd:KGW laser providing multi-watt output with excellent beam quality independent of resonator design and slope efficiency close to the theoretical maximum, offering the ultimate route for brightness-scaling in solid-state lasers.
Femtosecond operation of a solid-state laser passively mode locked by a quantum-dot saturable absorber has been demonstrated. Controllability of the pulse duration is demonstrated with pulses ranging from 58 ps to 158 fs around 1280 nm.
