通过对修正的非线性薛定谔方程的自相似性分析，研究了超短脉冲在具有增益和正（或正）四次色散的光纤中的传输。我们找到了一个精确的渐近解，对应于一个三角形状的T4/3强度分布，与T1/3啁啾，这是由数值模拟证实。与具有二次色散的常规情况相比，该解决方案遵循不同的幅度和宽度缩放。我们还建议，和数值研究，光纤激光器组成的组件具有正四次色散，发射四次自相似脉冲。
We study the propagation of ultrashort pulses in optical fiber with gain and positive (or normal) quartic dispersion by self-similarity analysis of the modified nonlinear Schrödinger equation. We find an exact asymptotic solution, corresponding to a triangle-like T4/3 intensity profile, with a T1/3 chirp, which is confirmed by numerical simulations. This solution follows different amplitude and width scaling compared to the conventional case with quadratic dispersion. We also suggest, and numerically investigate, a fiber laser consisting of components with positive quartic dispersion that emits quartic self-similar pulses.
