A classical particle oscillating in an arbitrary high-frequency or static field effectively exhibits a modified rest mass m eff derived from the particle averaged Lagrangian. Relativistic ponderomotive and diamagnetic forces, as well as magnetic drifts, are obtained from the m eff dependence on the guiding center location and velocity. The effective mass is not necessarily positive and can result in backward acceleration when an additional perturbation force is applied. As an example, adiabatic dynamics with m|| > 0 and m|| < 0 is demonstrated for a wave-driven particle along a dc magnetic field, m|| being the effective longitudinal mass derived from m eff . Multiple energy states are realized in this case, yielding up to three branches of m|| for a given magnetic moment and parallel velocity.

“…An accelerated electron in a strong laser field emits high-frequency radiation [2]. Its back-reaction on the electron motion can not be neglected, if in the frame where the electron is initially at rest, the energy radiated during the interaction time is comparable with mc 2 :…”

“…A high value of the integral in (2) may be reached, in principle, at the cost of higher intensity only, W ∼ 10 25 W/cm 2 . In the course of the ELI project (see [3]) * Electronic address: igorsok@umich.edu a laser is expected to reach focusable pulse energy of 1.5 kJ at λ ≈ 0.8µm, so the radiation effects will be dominant: W dt ≈ 2.1 kJ/(µm) 2 ≥ 1.2 kJ/(µm) 2 . Another opportunity may be realized while a strong laser pulse interacts with energetic electrons, which move oppositely to the direction of the pulse propagation.…”

We derive a modified non-perturbative Lorentz-Abraham-Dirac equation. It satisfies the proper conservation laws, particularly, it conserves the generalized momentum, the latter property eliminates the symmetry-breaking runaway solution. The equation allows a consistent calculation of the electron current, the radiation effect on the electron momentum, and the radiation itself, for a single electron or plasma electrons in strong electromagnetic fields. The equation is applied to a simulation of a strong laser pulse interaction with a plasma target. Some analytical solutions are also provided.

“…They range from pioneering studies of the radiation of a single electron driven by an electromagnetic wave [7,8], interaction of relativistic electrons under general initial conditions with such radiations [9], charged particle acceleration by simultaneous interaction with an electromagnetic wave and a static electric field [10,11], etc. Another important application of FEL principle is the particle acceleration by the inverse mechanism.…”
