Similarity for ultra-relativistic laser plasmas and the optimal acceleration regime
S. Gordienko, A. Pukhov
A similarity theory is developed for ultra-relativistic laser-plasmas. It is shown that the most fundamental S-similarity is valid for both under- and overdense plasmas. Optimal sc…

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…
