A petawatt (PW) beam line, which will deliver 1 kJ pulses with pulse duration near 1 ps, is being set up. Similar to the other high peak-power laser systems, the design of PW beam line also builds on chirped pulse amplification (CPA) techniques. Several new components except for the existing amplifier chain of the ninth beam in Shen-Guang-II (SG-II) facility are introduced, such as an optical parametric...
A Petawatt laser based on hybrid optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass has been demonstrated. This concept enables peak powers which can be scaled significantly beyond one petawatt. Higher power lasers enable access to unprecedented scientific research in the studies of high intensity physics. In this paper we discuss the laser, the potential of scaling to higher...
This study reports the construction of a Russian OPCPA-based laser complex. In this system, a 100 TW laser is taken as a front-end system, supplemented with a KD*P crystal with clear aperture of 20times20 cm, as another cascade of parametric amplification. The pump laser comes from one channel of the "Luch" facility with 2 kJ output pulse energy at the wavelength of 1054 nm. In addition,...
We have developed a chirped pulse amplification laser using Ndrglass zig-zag slab pumped by laser diodes as a higher-power pump source for intense few-cycle laser.

LFEX is a high-energy PW laser aiming for an output of 10 kJ/l-10 ps. In this paper the architecture of multi-pass chirped pulse amplifier with 2x2 arrayed structure, newly designed diamond-shape pulse compressor, pulse shaping technique and other technological developments are reported.
In order to meet the new requirements of the scientific research for high energy density physics, ICF, especially the fast ignition in inertial fusion energy, the upgrade program of SG-II facility has been carried. To achieve the performance goals of PW laser in SG-II facility, the enabling technologies about optical parametric chirped-pulse amplification (OPCPA), deformable mirrors and tiled gratings...
We demonstrate the generation of near-Fourier-limited 9.8 plusmn 0.3 fs laser pulses with an intensity exceeding a terawatt at 30 Hz repetition rate, using noncollinear optical parametric chirped pulse amplification. Amplified fluorescence is kept below 1%.
We report on a laser system developed as the front end for a multipetawatt-class laser that uses an optical parametric chirped-pulse amplifier as a preamplifier and a glass power amplifier. Early results are presented.
Summary form only given. Many laser plasma interaction experiments with ultrashort laser pulses either require or can significantly benefit from the use of a laser pulse with a temporal profile, which has been optimized for the experiment. We will first demonstrate experimentally that self-phase modulation is a serious issue for amplification of shaped pulses in chirped pulse amplification (CPA) systems...
