摘要：

A canonical quantization scheme is represented for a quantum system interacting with a non-linear absorbing environment The environment is taken anisotropic and the main system is coupled to its environment through some coupling tensors of various ranks The non linear response equation of the environment against the motion of the main system is obtained The non linear Langevin-Schrodinger equation is concluded as the macroscopic equation of motion of the dissipative system The effect of non-linearity of the environment is investigated on the spontaneous emission of an initially excited two level atom imbedded in such an environment (C) 2010 Elsevier Inc All rights reserved
