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.
