摘要

通过准线性激光唤醒场电子加速的一维模型，得到了电子束能量扩散对时间和注入持续时间的分析依赖关系，并以电子能量相对于等离子体波相位的相位肖像表示。与标准的气泡式方法相比，通过转移到具有另一种相位轨迹的去加速部分（通过降低等离子体波的振幅）来产生具有可变能量和较低能量分布的电子束的方法已经开发出来。分析得出的结果成功地描述了之前在齐姆巴罗夫等人（2024 arXiv:2403.19828）的实验和数值（PIC）数据中获得的关键特征。

Quasi-monoenergetic electron beam from LWFA: analytical approach

Analytical dependence of the energy spread of electron beam on time and injection duration has been obtained with the 1D model of the quasi-linear laser wakefield electron acceleration, presented as phase portraits of electron energy relative to the plasma wave phase. The method for producing electron beams with variable energy and a lower energy spread compared to a standard bubble-like approach by transferring to a deaccelerating part with another phase trajectory (by reducing the plasma amplitude of a wave) has been developed. The analytically obtained results successfully describe key features of the previously obtained in Tsymbalov et al (2024 arXiv:2403.19828) experimental and numerical (PIC) data.
