我们利用振荡器-放大器结构改进了13.9 nm高相干态X射线激光器。为了提高高亮度X射线激光器的性能，我们采用了行波泵浦的方式，将放大靶沿逆时针方向旋转3-4mrad。因此，可以利用放大靶的介质等离子体以高增益系数放大种子X射线激光。放大后的X射线激光的输出能量接近1.3mJ，相当于6.5×10(10)光子/脉冲的大光子通量和5×10(26)光子/(S中心点mm(2)中心点mrad(2)中心点0.01%带宽)的高峰值亮度。(C)2008年美国光学学会。
We have improved a highly coherent x-ray laser at 13.9 nm using an oscillator-amplifier configuration. To improve a high-brilliance x-ray laser, we adopted traveling wave pumping for the amplifier target and rotated the amplifier target 3-4 mrad in the counterclockwise direction. Thereby, a seed x-ray laser can be amplified by medium plasma of the amplifier target with a high gain coefficient. The amplified x-ray laser has the output energy of similar to 1.3 mu J, corresponding to a large photon flux of 6.5 x 10(10) photons/pulse and a high peak brilliance of 5 x 10(26) photons/ (S center dot mm(2)center dot mrad(2)center dot 0.01% bandwidth).
