X射线激光是激光物理与等离子物理中的一个重要研究领域。目前,X射线激光研究多采用毛细管放电、 高功率激光的多脉冲和短脉冲等抽运方式,而且绝大多数研究局限于软X射线波段。借鉴自由电子激光器的组成 结构,提出一种产生X射线激光的新方案:用钨制成毛细管的空心电极取代自由电子激光器内的摇摆器,内充特定 金属蒸气,如铜蒸气之类,使自由电子激光器变成自由电子抽运X射线激光器。运用电子碰撞电离、强流粒子束平 衡体系理论方程与等离子复合特性等理论对这种新型X射线激光器的工作原理及其方案的可行性作了进一步的 理论分析与探讨。X-ray lasers are an important area in the fields of laser and plasma physics. At present, the studies of X-ray lasers focus mostly on Z-pinch carbon discharge and the short and multiple laser pulse from high power lasers, and most of which confine in Soft X-ray laser. Inspired by the device of free-electron lasers, a newly designed device of X-ray laser is put forward. This device is converting free electron laser tool into free electron pumped laser tool through replacing wiggler by capillary hollow tungsten electrode which is full of specially metal steam such as copper steam. Its working principle and feasibility are analysed and proved by many theory such as electron impact ionization, equilibria system of high-energy particle beams and recombination properties of plasma produced.
