TL;DR: The detailed optical pulse structure of the short pulse free-electron laser depends on the synchronism between optical and electron pulses in the cavity as discussed by the authors, and it is shown that the instabilities associated with the limit cycle and chaotic behaviour can be examined by periodically adjusting the cavity desynchronism.

TL;DR: In this article, the authors proposed a method for characterising non-uniform density distributions of plasma by measuring the spectra of radiation emitted from a localised plasma dipole oscillator excited by colliding electromagnetic pulses.

TL;DR: In this paper, the authors have performed the first optical experiment using the laser output of the CLIO free electron laser (FEL) to explore the TPA theory to shorter wavelengths than hitherto available with the CO2 laser.

TL;DR: In this paper, a short seed pulse is amplified by a stretched and chirped pump pulse through Raman backscattering in a plasma channel, which excites a density echelon that acts as a "chirped" mirror and simultaneously backscatters and compresses the pump.
