Correlated Emission Laser and Quenching of Spontaneous Emission

Aditya Dahal

Abstract: In this paper, it is try to show that the quantum noise leading to the laser line width can be suppressed below the standard limit (Schalow-Townes limit) by preparing the atomic systems in a coherent superposition of states as in the Hanle -Effect and Quantum Beat experiments. In such coherently prepared atoms the spontaneously emission is said to be correlated.
