the envelope soliton is discribed by the density matrix. The Fokker-Planck equation of P representation is drawn from master equation in quantum optics. The quasiclassical nonlinear Schrodinger eguation is introduced for soliton envelope in an optical fiber. The application of the equation is discussed.
