我们发现当高强度脉冲与边界碰撞时，在时间边界附近形成时间边界孤子(TBS)，该孤子在非线性光学介质中运动。结果表明，新出现的TBS对由TBS与其它孤子产物之间的交叉相位调制引起的扰动是不稳定的，并且这种不稳定会引发反射脉冲系综强度的巨大起伏，对于即使是微弱起伏的输入脉冲，这种起伏的归一化自相关函数的幅度也是前所未有的。
We discover the formation of a temporal boundary soliton (TBS) in close proximity of a temporal boundary, moving in a nonlinear optical medium, upon high-intensity pulse collision with the boundary. We show that the emergent TBS is unstable to perturbations caused by the cross-phase modulation between the TBS and the other soliton products of the collision and that such instability triggers colossal intensity fluctuations of the reflected pulse ensemble with unprecedented magnitudes of the normalized autocorrelation function for an even weakly fluctuating input pulse.
