Accurate recovery of the two linewidths hidden in laser beatnote statistics
Jingming Chen, Yuanchen Qi, Yuzheng Pang +12
Photons from ultrastable lasers can remain coherent over distances approaching the Earth-Sun separation, enabling optical clocks projected to lose less than one second over the age…
