Physicists revive 1990s laser concept to propose a next-generation atomic clock

Researchers in the US and Germany propose a superradiant laser-based atomic clock built around a three-level atomic system that could run continuously with far less heating. Their calculations suggest an extremely narrow linewidth and much lower sensitivity to cavity vibrations, with possible uses beyond timekeeping in precision measurement and interferometry.
