| 摘 要： | 1.06μm激光以3.5×1013W/cm2管壁辐照强度注入带侧向喷口Mg微管靶管内。利用X射线条纹相机测量Mg10+和Mg11+离子沿侧喷方向发射X射线谱随时间变化过程,X射线时间分辨谱结果表明,三体再复合过程是实现Mg10+离子激发态1s4p和1s3p能级间粒子数反转的主要机制。用2660?紫外激光探针探测侧向喷口处等离子体电子密度,其密度值与用光谱分析获取的一致。

| Abstract: | The 1.06 μm laser with irradiance 3.5×1013W/cm2 was injected into Mg microtube target with lateral jet nozzle. The temporal evolution of X-ray spectra emitted from Mg10+ and Mg11+ ion along the side-blow direction was recorded by using X-ray streak camera. The results demonstrate that three-body recombination is the main mechanism to realize the strong population inversion between the excited state energy levels Is4p and Is3p of Mg10+ ion. The electron density in lateral jet nozzle measured by a 2660? UV laser probe coincides with density results deduced from the spectrum information.
