摘要：
Random spatial wave scattering and stochastic wave growth are studied where one or both of the random processes can be described by a Levy walk. This analysis extends previous work on randomly growing, and scattering waves where both the random processes are modeled by Gaussian diffusive statistics. Both random spatial scattering and stochastic wave growth modeled by Levy walks are studied separately. together. and in combination with Gaussian processes. Transmission coefficients. lasing thresholds. and energy densities in the medium are obtained for the different permutations.
