“…The first experiment to actually use laserbackscattered photons as a beam in a physics measurement was conducted at SLAC in 1969 (Ballam et al, 1969). Many other experiments followed this approach to produce x rays and γ rays (Albert et al, 2010;Anderson et al, 2004;Babzien et al, 2006;Bula et al, 1996;Burke et al, 1997;Glotin et al, 1996;Kotaki et al, 2000;Leemans et al, 1997;Litvinenko et al, 1997;Pogorelsky et al, 2000;Sakai et al, 2003;Sandorfi et al, 1983;Schoenlein et al, 1996;Ting et al, 1995;Yorozu et al, 2003Yorozu et al, , 2001, and nowadays several γ-ray facilities are based on this method.…”

Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the emergence of a novel generation of femtosecond x-ray sources. Based on radiation from electrons accelerated in plasma, these sources have the common properties to be compact and to deliver collimated, incoherent and femtosecond radiation. In this article we review, within a unified formalism, the betatron radiation of trapped and accelerated electrons in the so-called bubble regime, the synchrotron radiation of laser-accelerated electrons in usual meter-scale undulators, the nonlinear Thomson scattering from relativistic electrons oscillating in an intense laser field, and the Thomson backscattered radiation of a laser beam by laser-accelerated electrons. The underlying physics is presented using ideal models, the relevant parameters are defined, and analytical expressions providing the features of the sources are given. Numerical simulations and a summary of recent experimental results on the different mechanisms are also presented. Each section ends with the foreseen development of each scheme. Finally, one of the most promising applications of laser-plasma accelerators is discussed: the realization of a compact free-electron laser in the x-ray range of the spectrum. In the conclusion, the relevant parameters characterizing each sources are summarized. Considering typical laser-plasma interaction parameters obtained with currently available lasers, examples of the source features are given. The sources are then compared to each other in order to define their field of applications.Comment: 58 pages, 41 figure

“…Since then there have been numerous experimental observations of high-energy photons generated by scattering between relativistic electrons and laser pulses [36][37][38]. In the backscattering geometry (counterpropagating electron and laser beams) the duration of the generated x-ray pulse is determined by the electron bunch duration -typically several picoseconds or longer.…”

Femtosecond x-ray science is a new frontier in ultrafast research in which time-resolved measurement techniques are applied with x-ray pulses to investigate structural dynamics at the atomic scale on the fundamental time scale of an atomic vibrational period (~100 fs). This new research area depends critically on the development of suitable femtosecond x-ray sources with the appropriate flux (ph/sec/0.1% BW), brightness (ph/sec/mm 2 /mrad 2 /0.1% BW), and tunability for demanding optical/x-ray pump probe experiments. In this paper we review recently demonstrated techniques for generating femtosecond x-rays via interaction between femtosecond laser pulses and relativistic electron beams. We give an overview of a novel femtosecond x-ray source that is proposed based on a linear accelerator combined with x-ray pulse compression.

“…Alternative schemes rely on Thomson-and Comptonscattering [13][14][15][16], and recently also on the radiation from laser-plasma interactions [17][18][19][20]. The advancement of compact and powerful laser systems revived interest to these sources [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”
