Comment on "Dynamics of a Charged Particle" by F. Rohrlich [Phys. Rev. E 77, 046609 (2008), arXiv:0804.4614]

The equation derived by F. Rohrlich (Phys. Rev. E 77, 046609 (2008)) has been known for 60 years (C. J. Eliezer, Proc. Royal Soc. London. Ser. A 194, 543 (1948)). For a long time this equation has been considered to be incorrect. If there is any need to revisit this issue, the only relevant consideration is that the Eliezer equation is very difficult to solve numerically: the acceleration being expressed in terms of a function that, itself, depends on the acceleration.

Relativistic Whistle: High Order Harmonics Induced by the Ultra-Intense Laser Pulse Propagating inside the Fiber

A propagation of an ultra-intense short laser pulse in a fiber is investigated with two dimensional Particle-in-Cell simulations. The fiber is a narrow hollow channel with walls consisting of overdense plasma. In the nonlinear interaction of the laser pulse with fiber walls high order harmonics are generated. Sufficiently high harmonics, for which the fiber walls are transparent, propagate outwards at certain angle. This is a scheme of a generator of ultra-short pulses of coherent light with a very short wavelength.
