摘要
建立了适合描述短脉冲激光泵浦类Ｌｉ离子产生Ｘ射线激光的简化流体和原子动力学模型。短脉冲激光泵浦纤维靶产生等离子体的电子密度、电子温度、电离态分布等和驱动激光功率密度、脉宽及纤维靶半径相联系。研究了类Ｌｉ铝离子４ｆ－３ｄ跃迁激光增益系数随时间的演化过程，以及峰值增益和泵浦激光功率、脉宽及纤维靶半径之间的关系。
A compact model for the description of ultra-short pulse driven X-ray lasers in Li-like ions is established. Initial electron density, electron temperature and distribution of plasma of the fibre forget irradiated by ultra-short pulses have been related to the intensity and pulse duration of driving lasers and fibre radius.Evolution of Li-like aluminum ion Xray laser gains with time is investigated as well as peak gain dependencies upon the drivinglaser pulse intensity and the duration and fibre radius
