Acceleration of electrons and electromagnetic fields of highly intense laser pulses

Abstract

The acceleration of electrons by very intense lasers in vacuum is studied for different forms of laser pulses: finite plane and three-dimensional laser pulses. The latter case is treated by introducing an approximation of the laser frequency as a function of the Cartesian components of the wave number. Various examples which lead to high accelerations of electrons are given.

Amplification and Generation of Frequency-Modulated Soliton Pulses in Nonuniform Active Fiber Configurations

“…The critical part of laser physics is the development of ultrashort pulse generators (USPs), which provide a high peak radiation power [1,2]. Extremely high concentration of energy, broadband optical spectrum, and extremely short time of light emission [3][4][5] make the ultrashort pulse (USP) of great interest for many applications such as processing and modification of materials, laser micro-and nanostructuring of materials, and nuclear and accelerator technologies [1,2,[5][6][7][8][9][10][11]. Furthermore, high-frequency fiber lasers of USP with a repetition rate over 1 GHz are fabulous candidates for the development of radiophotonics technologies [12][13][14].…”

Electron acceleration in vacuum with two overlapping linearly polarized laser pulses

“…Because of the high intensity of the laser field, there has been continuous interest in electron acceleration in vacuum and numerous theoretical and experimental studies (Barton & Alexander, 1989;Esarey et al, 1995a;Malka & Miquei, 1996, Malka et al, 1997Hafizi et al, 1999;Stupakov & Zolotorev, 2000;Salamin & Keitel, 2002;Salamin et al, 2003;Huang & Wu, 2008;Schmid et al, 2009;Lourenco et al, 2010;Smorenburg et al, 2010;Xie et al, 2010;Li et al, 2011) have been performed in this field. However, shortcomings of many of those schemes are that the electron energy spread and the space spread both in transverse and longitudinal directions are very large, especially using linearly polarized laser pulse.…”
