本文描述了用时间分辨方法测量类镍银瞬态碰撞激发x射线激光输出的实验结果。超快X射线条纹相机被用来诊断输出的$J=\stackrel{\ensuremath{\rightarrow}}{0}1 $$4d\ensuremath {-}4p$激光线在13.9 nm。在最佳泵浦激光照射条件下，测得X射线脉冲半高宽为1.9\ifmmode\pm\else\textpm\fi {}0.7 \mathrm{ps}$。这是迄今为止直接证明的最短X射线激光持续时间，并说明瞬态X射线激光器作为高亮度皮秒X射线源的巨大潜力。
A time-resolved measurement of the output from the Ni-like Ag transient-collisional-excitation x-ray laser is described. An ultrafast x-ray streak camera was used to diagnose the output of the $J=\stackrel{\ensuremath{\rightarrow}}{0}1$ $4d\ensuremath{-}4p$ lasing line at 13.9 nm. The full width at half maximum duration of the x-ray pulse is measured to be of $1.9\ifmmode\pm\else\textpm\fi{}0.7 \mathrm{ps}$ at optimum conditions of pump laser irradiation. This is the shortest x-ray laser duration directly demonstrated to date and illustrates the great potential of transient x-ray lasers as a high brightness, picosecond x-ray source for applications.
