A framework for continuous superradiant laser operation via sequential transport of atoms

Bruno Bellomo, Jana El Badawi, Marion Delehaye

Synchronization of two atomic ensembles in a shared cavity produces a single narrow superradiant line at their weighted average frequency.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find for balanced and imbalanced atom numbers that synchronization leads in a certain parameter space to a single narrow spectral line whose central frequency follows the weighted average frequency.

C2weakest assumption

Atoms within each ensemble have identical detunings and equal coupling strengths to the cavity, while the two ensembles differ only in their common detuning value; this equal-coupling and equal-detuning premise is stated for the two-site configuration and is required for the synchronization result to produce a single weighted-average line.

C3one line summary

Sequential transport of two 171Yb atomic ensembles into a shared cavity enables continuous superradiant emission with tens of picowatts power, sub-millihertz linewidth, and a single spectral line at the weighted-average frequency via dipole synchronization.
