A Note on the Second Order Optical Process for a Solvable Model of Microscopic Phase Modulation to Intermediate State

Abstract

The second order optical process is investigated by a solvable model of microscopic phase modulation in which a intermediate state is affected by a boson system. In the weak coupling limit, the model reduces to the case of Gaussian Markovian stochastic modulation of the intermediate state. As the model is exactly solvable, the non-Markovian effect of the boson modulation system can be explicitly studied with the temperature dependence.
