Description

The problem of generation of twisted photons is well studied theoretically and is promising due to possible applications /1/. There are already prototypes of devices producing such photons in various energy ranges. The most developed area of research is optical and radio ranges.
Earlier we presented the results of research on generation of twisted photons by relativistic particles in strong laser fields with circular polarization. Calculations of the emission spectra of twisted photons were carried out taking into account the radiation reaction.
In this report we consider another way of generating hard twisted photons – the radiation caused by the motion of charged particles in the field of a strong laser wave with linear polarization. The results of numerical modeling of the orbital angular momentum per photon as a function of photon energy are presented. The effect of a blooming rose is demonstrated. A comparative analysis with the results of /2/ is given.
