The complete basic equations for (2+1) -dimensional self-trapped beam propagation in photorefractive media are numerically solved, with the anisotropic nonlocal response, diffusion, and space-charge-field displacement effects taken into account. Initial Gaussian beams show elliptical beam shapes, self-deflection, and long-lived oscillations after propagation. The critical parameters that determine the possible damping of the transients are discussed.
对光折变介质中(2 + 1)维自陷光束传播的完整基本方程进行了数值求解，其中考虑了各向异性非局部响应、扩散和空间电荷场位移效应。初始高斯光束在传播后呈现出椭圆光束形状、自偏转和长时间的振荡。讨论了决定瞬态可能阻尼的关键参数。
