摘要

稀土掺杂晶体可以模拟为非均匀展宽的两能级原子。光束在晶体中的传播可以用麦克斯韦-布洛赫方程来描述。本文采用fft有限差分光束传播法对麦克斯韦方程组进行数值求解，采用有限差分法对布洛赫方程组进行数值求解。给出了离轴三脉冲光子回波的数值模拟结果。

Simulations of 2D Maxwell-Bloch equations

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.
