理论研究和数值模拟研究表明激光在等离子体中诱导的等离子体密度调制可以起类似布拉格反射镜的作用,使得后面的入射光在等离子体平均密度远低于临界密度的区域就对入射光产生相位反射.相位反射的发生会影响激光在等离子体中的传播,例如激光在等离子体中相对传播时会出现激光场空洞现象.进一步的理论和数值模拟研究表明,相位反射持续发生的时间以及反射率的高低与等离子体的密度、等离子体区域的长度、激光强度以及脉宽等因素密切相关,这些都会对激光在等离子体中的传输产生影响.
Theoretical studies and numerical simulations show that the laser induced plasma density modulation in the plasma can function like a Bragg reflector such that the incoming incident light produces a phase of incident light when the average plasma density is well below the critical density Reflection. The occurrence of phase reflections will affect the laser propagation in the plasma, for example, the laser field in the plasma relative to the laser field will appear when the hole phenomenon.Further theoretical and numerical simulation studies have shown that the phase reflections continue to occur as well as the reflectivity The level of the plasma is closely related to the density of the plasma, the length of the plasma region, the intensity of the laser, and the pulse width, all of which influence the laser transmission in the plasma.
