| 摘 要： | 通过调节二阶啁啾参数和空间非均匀效应对高次谐波光谱进行了优化.结果表明：在长脉宽负向啁啾和负向非均匀效应组合下，谐波光谱截止能量和强度得到最佳增大，并获得X射线范围内的光谱连续区.最后，通过叠加光谱连续区上的部分谐波可获得一个脉宽仅为23 as的孤立脉冲.

| Abstract: | The high order harmonic spectrum is optimized by controlling the second order chirp parameter and the spatial inhomogeneous effect. The results show that under the combination of long pulse duration negative chirp and negative inhomogeneous effect, the cutoff energy and intensity of harmonic spectrum are optimally increased, and the spectral continuum in the X-ray range can be obtained. Finally, an isolated pulse with a duration of 23 as can be obtained by superposing some harmonics on the spectral continuum. |

| Keywords: | high-order harmonic generation attosecond pulses second order chirp pulse spatial inhomogeneous pulse |
