论文摘要
具有空间非均匀极化分布的矢量梁对于许多应用非常重要，因为其独特的场特性和与物质相互作用时的新作用。在这里，通过三维粒子中的粒子模拟，我们证明了极端硫酸群至X射线光谱区域中的强烈矢量梁可以通过相对论方案中的高谐波生成（HHG）产生。在相对论等离子体镜的极端非线性HHG动力学期间，可以将基本激光束的向量特征转移到较高的频率发射中。可以将矢量谐波梁合成为Attosecond向量梁。也可以产生携带轨道角动量的矢量谐波光束。这种明亮的涡旋和矢量光源在各种应用中提供了新的机会，例如具有高空间和时间分辨率，超快磁光谱和颗粒操作的成像。
Vector beam, with a spatial nonuniform polarization distribution, is important for many applications due to its unique field characteristics and novel effects when interacting with matter. Here through three-dimensional particle-in-cell simulations, we demonstrate that intense vector beams in the extreme-ultraviolet to x-ray spectral region can be generated by means of high harmonic generation (HHG) in the relativistic regime. The vector features of the fundamental laser beam can be transferred to the higher frequency emission coherently during the extreme nonlinear HHG dynamics from relativistic plasma mirrors. The vector harmonic beams can be synthesized into attosecond vector beams. It is also possible to generate vector harmonic beam carrying orbital angular momentum. Such bright vortices and vector light sources present new opportunities in various applications such as imaging with high spatial and temporal resolution, ultrafast magnetic spectroscopy, and particle manipulation.
