Frequency measurements of superradiance from the strontium clock transition
Matthew A. Norcia, Julia R. K. Cline, Juan A. Muniz +6
We present the first characterization of the spectral properties of superradiant light emitted from the ultra-narrow, 1 mHz linewidth optical clock transition in an ensemble of col…

1.5 m lasers with sub 10 mHz linewidth
D. G. Matei, T. Legero, S. Häfner +8
We report on two ultrastable lasers each stabilized to independent silicon Fabry-Pérot cavities operated at 124 K. The fractional frequency instability of each laser is completely…
