Energy partitioning and electron momentum distributions in intense laser-solid interactions

Joel Magnusson, Arkady Gonoskov, Mattias Marklund

摘要:

通过强激光脉冲作用于固体目标产生向内取向的高能电子流是将激光能量转移到粒子的最强大和最容易获得的方法,这是从TNSA到实验室天体物理学的众多应用的基础。具有激光波长尺度的结构可以显著增强能量吸收,这在最近的研究中一直是关注的中心。在这篇文章中,我们证明和评估的结构,扩大所产生的高能电子的角分布的效果。我们分析了PIC模拟的结果,并揭示了几个方面,可以是重要的相关应用。

英文摘要:

Producing inward orientated streams of energetic electrons by intense laser pulses acting on solid targets is the most robust and accessible way of transferring the laser energy to particles, which underlies numerous applications, ranging from TNSA to laboratory astrophysics. Structures with the scale of the laser wavelength can significantly enhance energy absorption, which has been in the center of attention in recent studies. In this article, we demonstrate and assess the effect of the structures for widening the angular distribution of generated energetic electrons. We analyse the results of PIC simulations and reveal several aspects that can be important for the related applications.
