从理论上和实验上观察了激光谐振腔中超短抛物线脉冲的自相似传播。这构成了锁模激光器中的一种新型脉冲整形：与众所周知的静态（类孤子）和呼吸（色散管理孤子）脉冲演化相反，在大多数激光腔中观察到控制脉冲传播的非线性波动方程的渐近解。稳定的自相似脉冲的能量远大于类孤子脉冲整形所能承受的能量，这对实际激光器具有影响。
Self-similar propagation of ultrashort, parabolic pulses in a laser resonator is observed theoretically and experimentally. This constitutes a new type of pulse shaping in mode-locked lasers: in contrast to the well-known static (solitonlike) and breathing (dispersion-managed soliton) pulse evolutions, asymptotic solutions to the nonlinear wave equation that governs pulse propagation in most of the laser cavity are observed. Stable self-similar pulses exist with energies much greater than can be tolerated in solitonlike pulse shaping, and this has implications for practical lasers.
