Victor Yanovsky,Vladimir Chvykov,G. Kalinchenko,Pascal Rousseau,Thomas A. Planchon,Takeshi Matsuoka,Anatoly Maksimchuk,John Nees,Gilles Chériaux,Gerard Mourou,Karl Krushelnick +10 more
TL;DR: To the knowledge, this is the first multi-100TW-scale laser at 0.1 Hz repetition rate and booster amplifying stage to the 50-TW-Ti:sapphire laser (HERCULES).
Journal ArticleDOI

TL;DR: In this paper, the authors review recent achievements with ultrafast bulk lasers and amplifiers based on Yb:YAG and yb:glass and pay attention to those aspects of the quasi-three-level nature of gain media that are important for short-pulse generation.
Journal ArticleDOI
Multiple colliding electromagnetic pulses: a way to lower the threshold of e+ e- pair production from vacuum.
TL;DR: The scheme of a simultaneous multiple pulse focusing on one spot naturally arises from the structural features of projected new laser systems, such as the Extreme Light Infrastructure and High Power laser Energy Research (HiPER).
Journal ArticleDOI
Relativistic generation of isolated attosecond pulses in a lambda 3 focal volume.
TL;DR: This work has found that single 200 attosecond pulses could be produced efficiently in a lambda(3) laser pulse reflection, via deflection and compression from the relativistic plasma mirror created by the pulse itself.
Journal ArticleDOI
Diode-pumped Kerr-lens mode-locked Yb:KY(WO 4 ) 2 laser
TL;DR: A self-starting Kerr-lens mode-locked Yb:KY(WO(4))(2) laser directly end pumped by two 1.6-W diodes is demonstrated for what is to the authors' knowledge the first time.
