How dielectric, metallic and liquid targets influence the evolution of electron properties in a pulsed He jet measured by Thomson and Raman scattering

“…, that is if the laser wavelength λ L is much smaller than the Debye length λ D , the scattering is incoherent [44][45][46]. This condition is met for the discharge under study, where the maximum electron density of 10 2 m −3 and typical electron temperature of 2eV result in α=0.06.…”

“…Thomson scattering. When scattered light is collected perpendicular to the polarization of the laser, the differential cross section of Thomson scattering reduces to the classical electron radius squared[44][45][46]:…”

Influence of initial phase on radiation characteristics of electrons driven by non-tightly focused laser

“…Since the emergence of chirped pulse amplification (CPA) technique at the end of last century, people have become more interested in relativistic nonlinear Thomson scattering Many scholars have focused on the field of strong laser-matter interaction, especially in the direction of ultrafast laser physics [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Using the classical theory of electron Thomson scattering, Zheng [9] discussed the effect of different electron initial states and laser field parameters on the directionality and radiation efficiency of the radiation pulse.…”

“…In recent years in the field of x-ray sources, along with the development of intense laser pulses, Thomson scattering has received a lot of attention due to its unique characteristics, and has promising applications in many fields such as modern astrophysics, imaging and information technology [18][19][20].…”

Effect of pulse width variation on the radiation characteristics of electrons driven by circularly polarized lasers

“…[23] In recent years, x-rays have shown promise in astrophysics, medical imaging and therapy, and information. [18][19][20] In order to better apply x-rays to these fields, it is important and relevant to study the phenomenon of ray generation and to better control the characteristics of the rays and perform targeted ray modulation in the future.…”
