我们观察了微结构光纤中脉冲捕获的动力学。几个周期的脉冲创建一个系统的两个脉冲：一个拉曼移位孤子陷阱的脉冲在正常的色散制度。当孤子接近零群速度色散的波长时，拉曼位移突然终止，被捕获的脉冲被释放。特别地，陷阱的长度小于4ps，并且包含1ps的脉冲。在被释放之后，该脉冲不对称地扩展到超过10 ps。此外，在高输入脉冲能量下，随着超连续谱的进一步发展，捕获动力学没有扰动。
We observe the dynamics of pulse trapping in a microstructured fiber. Few-cycle pulses create a system of two pulses: a Raman shifting soliton traps a pulse in the normal dispersion regime. When the soliton approaches a wavelength of zero group velocity dispersion the Raman shifting abruptly terminates and the trapped pulse is released. In particular, the trap is less than 4 ps long and contains a 1 ps pulse. After being released, this pulse asymmetrically expands to more than 10 ps. Additionally, there is no disturbance of the trapping dynamics at high input pulse energies as the supercontinuum develops further.
