“…The rapid progress of chirp amplification technology has had a great effect on the development of high-power laser [25][26][27]. The symmetry of the pulse is broken by the use of chirped laser pulse, and the amplitude of nonlinear plasmawake wave is increased in comparison to the nonchirped laser pulse [28].…”

We study the effect of nonlinearly chirped super-Gaussian (SG) laser pulse on wakefield generation in an inhomogeneous plasma. The different types of nonlinearly chirped pulse are employed, and different kinds of inhomogeneous plasma density are used. The maximum wakefield amplitude as the function of nonlinearly chirped laser pulse and inhomogeneous plasma density in parameter space are obtained. Moreover, the dependence of the maximum wakefield amplitude on the SG laser pulse index is discussed. This shows that a larger wakefield can be obtained when the chirped pulse and inhomogeneous density are in the critical regions. Wakefield generation can be controlled by adjusting the chirped SG pulse and inhomogeneous plasma density parameters. That is, we provide an efficient way for the controlled generation of the wakefield.

“…[1][2][3][4][5][6][7][8] Lots of developments of ultrashort high power lasers have been carried out with progress in ultrashort laser technologies such as chirped pulse amplification. [9][10][11][12][13] The interaction of an intense short laser pulse with under dense plasma can produce accelerating gradients, thousands of times, higher than conventional accelerators. [14][15][16] Plasma wake can travel at the group velocity of laser pulse, close to the speed of light, in order to accelerate particles up to relativistic velocities.…”

An ultrashort laser pulse propagating in plasma can excite a nonlinear plasma wake field which can accelerate charged particles up to GeV energies within a compact space compared to the conventional accelerator devices. In this paper, the effect of different kinds of nonlinear chirped Gaussian laser pulse on wake field generation is investigated. The numerical analysis of our results depicts that the excitation of plasma wave with large and highly amplitude can be accomplished by nonlinear chirped pulses. The maximum amplitude of excited wake in nonlinear chirped pulse is approximately three times more than that of linear chirped pulse. In order to achieve high wake field generation, chirp parameters and functions should be set to optimal values.

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 .
