156 µm 1 watt single frequency semiconductor disk laser

A single frequency wafer-fused semiconductor disk laser at 1.56 mu m with 1 watt of output power and a coherence length over 5 km in fiber is demonstrated. The result represents the highest output power reported for a narrow-line semiconductor disk laser operating at this spectral range. The study shows the promising potential of the wafer fusion technique for power scaling of single frequency vertical-cavity lasers emitting in the 1.3-1.6 mu m range.
