Coherent Harmonic Focusing and the Light Extreme
S. Gordienko, A. Pukhov, O. Shorokhov +1
We demonstrate analytically and numerically that focusing of high harmonics produced by the reflection of a few femtosecond laser pulse from a concave plasma surface opens a new wa…

Table-top synchrotron
S. Kiselev, A. Pukhov, I. Kostyukov
Using three-dimensional particle-in-cell simulations we show that a strongly nonlinear plasma wave excited by an ultrahigh intensity laser pulse works as a compact high-brightness…

Spontaneous and Stimulated Synchrotron Radiation from Relativistic Electrons in Ion Channel
I. Kostyukov, A. Pukhov
Spontaneous and stimulated emission of an electron in the ion channel is studied. The emission processes are studied in the regime of high harmonic generation when the parameter of…
