In this article we briefly review three generation mechanisms of high-energy photons related, directly or otherwise, to high-intensity laser–matter interactions. The three mechanisms are the “Betatron Radiation” (BR), the “Parametric X-ray Radiation” (PXR) from Laser-WakeField Accelerated Electrons (LWFA), and the all-optical “Compton BackScattering” (CBS). The aim is to highlight similarities and differences, in particular regarding the phase-matching conditions for the high-energy photons to be emitted.

Abstract
In this article we briefly review three generation mechanisms of high-energy photons related, directly or otherwise, to high-intensity laser–matter interactions. The three mechanisms are the “Betatron Radiation” (BR), the “Parametric X-ray Radiation” (PXR) from Laser-WakeField Accelerated Electrons (LWFA), and the all-optical “Compton BackScattering” (CBS). The aim is to highlight similarities and differences, in particular regarding the phase-matching conditions for the high-energy photons to be emitted.File in questo prodotto:
