A femtosecond laser pulse lasts on the order of a quadrillionth of a second but reaches a peak power equivalent to that of the entire power grid of North America during its short burst.
这种飞秒激光脉冲持续兆分之一秒(千万亿分之一秒)的时间，但是在其短暂的持续时间内，功率峰值可以达到北美电网功率相当的水平。
The higher the initial relative peak power is, the higher the compression ratio and compressed peak power of the bright pulse are.
初始相对峰值功率愈高，亮脉冲的压缩比和压缩后的峰值功率愈高，同时所需的光纤长度愈短。
The results show that the compression ratio and compressed peak power of the bright pulse depend upon the initial relative peak power of the dark pulse to the bright pulse.
结果表明，亮脉冲的压缩程度与暗孤子相对于亮脉冲的初始峰值功率有关。
