    The Multiple Scattering of Laser Beam Propagation in Advection Fog and Radiation Fog by Qiang Xu, Yunhua Cao, Yuanyuan Zhang, Shaohui Yan, Yiping Han, Zhensen Wu

    Published 2023-01-01
    “…The characteristics of laser beam scattering in different types of fogs are studied based on the droplet size characteristics of advection fog and radiation fog, the scattering coefficients of droplets with different laser wavelengths(0.86 μm, 0.91 μm, 1.06 μm, 1.3015, and 10.6 μm) are calculated, the multi scattering of laser beam is studied by the Monte Carlo method, the propagation path and scattering direction of photons is analyzed, relations between asymmetry factor, albedo of fog droplets, and the visibility are presented, and the forward scattering intensity and the backward scattering intensity versus scattering angle are gotten and discussed.…”

    Recent Advances in Graphene-Assisted Nonlinear Optical Signal Processing by Jian Wang, Xiao Hu

    Published 2016-01-01
    “…So far, the main focus has been on graphene based photonics and optoelectronics devices. Due to the linear band structure allowing interband optical transitions at all photon energies, graphene has remarkably large third-order optical susceptibility χ(3), which is only weakly dependent on the wavelength in the near-infrared frequency range. …”
