Bow wave in laser plasma and electron acceleration

利用数值模拟和突变理论，揭示了高次谐波产生的弓波诱导机制。这种机制的可行性在3D和2D PIC模拟中得到了成功的验证。该机制和模拟解释了最近用太瓦激光进行的实验中看到的XUV光谱区域的高次谐波。提出了一种基于高次谐波产生机理的新型XUV光源和X射线光源的研制。

The bow wave induced mechanism of high-order harmonics generation was discovered using simulations and catastrophe theory. This mechanism feasibility was successfully demonstrated in 3D and 2D PIC simulations. The mechanism and the simulations explained high-order harmonics in the XUV spectral region seen in recent experiments with terawatt lasers. Development of new XUV light and X-ray source based on the high-order harmonics generation mechanism is proposed.
