我们确定了一个物理场景，即峰值功率超过自聚焦临界功率几十年的光场波形可以自压缩到子周期脉冲宽度。与光束分裂，强烈的热点，和避免在脉冲压缩长度内的材料的光学损伤，通过保持这个长度短于调制不稳定的积累长度，光束被示出保持其连续性的点的子周期脉冲产生。
We identify a physical scenario whereby optical field waveforms with peak powers several decades above the critical power of self-focusing can self-compress to subcycle pulse widths. With beam breakup, intense hot spots, and optical damage of the material avoided within the pulse compression length by keeping this length shorter than the modulation-instability buildup length, the beam is shown to preserve its continuity at the point of subcycle pulse generation.
