| contents | Twisted photons can be emitted by free electrons in circular or spiral motion, which carry orbital angular momentum (OAM) and possess a helical phase structure. However, classical radiation reaction (RR) effects has not been investigated as an accelerated electron emits vortex radiation during the interaction with a electromagnetic field. This work focuses on investigating the effects of radiation reaction on the production of twisted photons in the Nonlinear Inverse Thomson Scattering (NITS) process. Using the precise electron trajectory obtained by Landau-Lifshitz (LL) equation with a circularly polarized (CP) plane-wave field, we find that the radiation reaction effects can be significant for a sufficiently long pulse of a plane wave. They observe modifications in the frequency, phase structure, rotational asymmetry of OAM density, and energy distribution of the vortex field due to radiation reaction. This finding could provide an unique signature for the detection of radiation reaction. |
