Simulations of 2D Maxwell-Bloch equations

摘要

Rare-earth-doped crystals can be modelled as inhomogeneously broadened two-level atoms. Beam propagation in the crystals can be described by the Maxwell-Bloch equations. We numerically solve Maxwell''s equations by using the FFT-finite difference beam propagation method and the Bloch equations by using the finite difference method. Numerical simulation results are given for an off-axis 3-pulse photon echo.
