摘要/Abstract

摘要： 用变分法研究了强非局域非线性损耗介质中1+1维厄米高斯光束的传输特性，得到了损耗光束参量在介质中传输所遵循的规律及其形成损耗光孤子所需要的临界功率．当初始功率接近临界功率时，光束的束宽按准正弦或准余弦规律作准周期展宽变化．通过比较，利用变分法所得到的解析解与数值解在光束传输一段较长的距离内都符合的比较好．

Abstract: The propagation properties of （1+1）D Hermite--Gauss beam in nonlocal nonlinear lossy media are investigated by using variational methods. The laws of beam parameters followed when propagating in medium and the critical power required by forming the lossy solitons are obtained. When the initial power is close to the critical power, the beam width expands periodically and obeys the quasi-sine or quasi-cosine law. By comparison, the analytical solutions and numerical solutions using the variational solution method are in good agreement with a longer distance in beam propagation.
