1.5 μm lasers with sub 10 mHz linewidth [PDF]
Conference on Lasers and Electro-Optics, 2017 We report on two ultrastable lasers stabilized to single-crystal silicon Fabry-Pérot cavities at 124 K. The lasers show unprecedented thermal noise-limited frequency instabilities of 4×10−17 and linewidths below 10 mHz.
