Kid in the undeworld
It's a small figure
walking slowly, in the world where
everything was misty, with endless water supply
but not much else
the sight of his small hands
the sight of his hair
seen through a worn rain hat.
He holds a bow of rice
and a pair of bronze bells
chirping in time
with each footstep. |

发帖数: 720 | 17 The leaves of trees rustled in the wind, like somebody’s chuckling. Birds
chirped in the dreams. If you held your breath and pricked up your ears, you
’d hear the fallen leaves glide on the ground, the various crackling when
they rolled over the roots and grass, and worms’ sneaking in the earth and
bats’ fluttering in the wind. Sometimes you could hear hoofs and sighs far
far away……they came and went now and then, distinct from the heart-breaking
music, and were the most ordinary nonetheless. |

Raindrops on the steps, the night drizzled.
Cold and alone in bed, as time trickled.
Should I look in the mirror, my face would be smile dimpled.
Languid hair unbound, jade petals unjeweled.
Leaning over the terrace,
Can't stop thinking, the willows sweeping, this time of spring.
How I envy the innocent swallows, passing by the rails, chirping.
For my love bid me farewell, all these years of longing.
I am dying to be a cuckoo, come back, come back, I will be calling. |

什么示波器也满足不了你的要求，因为没有任何探测器能有100fs以内的响应速度。
也许最新的streak camera能有这么快？我很怀疑。
激光器出来的电信号和光信号完全不是一回事，只能用来做同步触发的信号，不能
反映光信号的带宽或其他任何信息。
要看超快光脉冲的波形，最简单的是自己搭一个autocorrelator，利用SHG或者硅探
测器的双光子吸收，从autocorrelate的信号反推计算出信号本身波形出来。
如果想看chirp或者光脉冲波形比较复杂，可以搭一个SPIDER或者FROG，不过那样就
很复杂了。

我觉得阿秒挺有意思的，不过这个领域已经不是激光技术领域的，而是使用超短脉冲的
激光作为工具，进行物理层面的研究
另外，光纤激光器肯定是未来的一个大方向，无论是连续 还是超短脉冲，我觉得很有
前景。个人见解，敬请指正！

阿秒脉冲，其原理是选取多个频段的高次谐波，如果他们之间相位差恒定，那么就可以
相干叠加产生短脉冲激光，和锁模激光很像。如果使用few-cycle的激光，就可能产生
单个阿秒脉冲，可能，如果要确定呢，就需要稳定激光电场与包络的相位（carrier-
