Fokker Planck

A theory of two-photon phase-sensitive amplifier based on two-photon cascade is presented. The atomic coherence is produced by means of two dipole-allowed transitions driven by coherent fields; a practical alternative versus scheme employing coupling between dipole-forbidden levels. The regime of parameters under which a laser signal can be phase locked and amplified is discussed through the corresponding Fokker–Planck equation.
