电离调制 meaning in Chinese

ionic beam modulation

Starting from maxwell ' s equations , the paraxial propagation equation of intense laser light in ionizing gases is derived and is analyzed by means of the source - dependent expantion ( sde ) method . an equation governing the evolution of the laser beam redius is obtained , based on which we analyze the ionization - modulation ( im ) instability . then , a vectorial , nonparaxial propagation equation is established , and the mechanism of energy loss during the propagation is analyzed
首先从maxwell方程组出发推导出强激光在电离气体中传输的傍轴传输方程，利用源展开方法对傍轴传输方程进行分析，得到光束半径的演化方程，从而讨论传输过程中的电离调制不稳定性；再建立矢量非傍轴模型，并讨论气体电离产生等离子体所引起的激光能量损耗机制。
