Description

Lasers and masers typically require population inversion. But with phase coherent atoms (phasers), we get lasing without inversion (e.g., 10% of the atoms excited). Now we find that it is possible to get coherent light emitted with no atoms excited, via Quantum Amplification of Superradiant Emission of Radiation (QASER).
