“…Thus, we identify a pump intensity window for favorable amplification, and show that the recent experimental data apparently falls within this intensity window. These deductions follow from previously published results [13,14] as well as new experiments which compare the "forward chirp" with the "reverse chirp".…”

“…1. We focus here on just those features of the experiment which will be analyzed later in the paper; further details of the experiment and the full experimental results can be found in [13,14]. Note that both the seed pulse and the pump pulse are generated by the same femtosecond Ti:Sapphire laser.…”

A plasma-based resonant backward Raman amplifier/compressor for high power amplification of short laser pulses might, under ideal conditions, convert as much as 90% of the pump energy to the seed pulse. While the theoretical highest possible efficiency of this scheme has not yet been achieved, larger efficiencies than ever before obtained experimentally (6.4%) are now being reported, and these efficiencies are accompanied by strong pulse compression. Based on these recent extensive experiments, it is now possible to deduce that the experimentally realized efficiency of the amplifier is likely constrained by two factors, namely the pump chirp and the plasma wavebreaking, and that these experimental observations may likely involve favorable compensation between the chirp of the laser and the density variation of the mediating plasma. Several methods for further improvement of the amplifier efficiency in current experiments are suggested.

“…Plasmas can also be used to manipulate the basic properties of light waves, which could revolutionize the design and applications of high-power lasers; the use of plasma in lieu of conventional optics alleviates the constraints associated with optic damage, which is currently one of the main factors driving the size and cost of large-scale laser facilities. Examples of plasma-based optical components include: plasma mirrors [5], which can be used to redirect, focus, and improve the contrast of laser beams; plasma gratings, which are routinely used at the National Ignition Facility to tune the implosion symmetry of ICF targets by facilitating power transfer between intense lasers [6][7][8]; laser amplifiers [9,10]; and laser compressors [11]. More recently, we showed theoretically that plasmas could also be used to dynamically control the polarization of light waves [12].…”

“…Understanding laser-plasma impacts on polarization is critical in situations in which polarization affects both laser absorption and ion acceleration mechanisms [17,18]. Finally, plasma-mediated polarization control complements the suite of existing plasma-based light manipulation schemes (including mirrors [5], gratings [6][7][8], amplifiers [9,10], and compressors [11]), raising the possibility of an entirely plasma-based laser system operating at fluences many orders of magnitude larger than conventional laser systems.…”

The high-power femtosecond laser has now become an excellent scientific tool for the study of not only relativistic laser-matter interactions but also scientific applications. The high-power femtosecond laser depends on the Kerr-lens modelocking (KLM) and chirped-pulse amplification (CPA) technique. An all-Ti:sapphire-based 30-fs PW CPA laser, which is called the PULSER (Petawatt Ultrashort Laser System for Extreme Science Research) has been recently constructed and is being used for accelerating the charged particles (electrons and protons) and generating ultrashort high-energy photon (X-ray and γ -ray) sources. In this review, the world-wide PW-level femtosecond laser systems are first summarized, the output performances of the PULSER-I & II are described, and the future upgrade plan of the PULSER to the multi-PW level is also discussed. Then, several experimental results on particle (electron and proton) acceleration and X-ray generation in the intensity range of mid-10 18 W/cm 2 to mid-10 20 W/cm 2 are described. Experimental demonstrations for the newly proposed phenomena and the understanding of physical mechanisms in relativistic and ultrarelativistic regimes are highly expected as increasing the laser peak intensity up to over 10 22 W/cm 2 ∼10 23 W/cm 2 .
