Numerical analysis of a superradiance-sideband-assisted laser with a zero frequency pulling and a narrow linewidth ...
Numerical simulations based on the quantum Langevin equations have been performed for a large number of two-level atoms in a beam interacting with a low-Q cavity with the atomic initial superposition states close to the north pole of the Bloch sphere. When the pump Rabi frequency was modulated at $Δ...
