基于高斯型脉冲驱动的类镍瞬态X射线激光的流体力学模型

Hydrodynamic model of transient Ni-like X-ray lasers driven by Gaussian laser pulse

在激光脉冲为高斯型的条件下对瞬态X射线激光的流体力学自相似模型进行了修正,并将计算结果与自相似模型解析解的结果进行了比较.研究表明,修正模型的结果比解析解更为精确,从而验证了新模型的可靠性.利用该模型对类镍钼X射线激光实验进行了优化设计,得到了优化的实验方案.

The self-similarity model of hydrodynamics of transient collisional excitation X-ray lasers is modified for drive laser pulse with a Gaussian temporal profile. The results show that the modified model can more accurately describe the hydrodynamic process of tramsient collision emission X-ray laser than the self-similarity model. Using the modified model, the experimental design of the Ni-like Mo X-ray lasers is optimized.
