摘　　要：We investigate how an optical squeezed chaotic field（SCF） evolves in an amplitude dissipation channel. We have used the integration within ordered product of operators technique to derive its evolution law. We also show that the density operator of SCF can be viewed as a generating field of the squeezed number state.We investigate how an optical squeezed chaotic field（SCF） evolves in an amplitude dissipation channel.
