Quantum polarization fluctuation of a multi-Gaussian Shell-model beam in a slant turbulent channel

The influence of atmospheric turbulence on the quantum polarization fluctuations of multi-Gaussian Schell-mode (MGSM) beams is studied in detail. An analytical formula for the quantum degree of polarization of a MGSM beam propagating in a slant turbulent channel is derived. Our results show that the degree of polarization of a MGSM beam is affected more by the atmospheric turbulence than that of a GSM beam. The numerical simulations also show that a MGSM beam with higher photon-number level, shorter wavelength, bigger transverse beam width is less affected by the turbulence.
