Optimization of laser parameters for proton acceleration using double laser pulses in TNSA mechanism
Saurabh Kumar,Devki Nandan Gupta +1 more
TL;DR: In this article, the authors investigated the optimization of laser parameters for proton acceleration using double laser pulses in the target normal sheath acceleration (TNSA) mechanism, and found that the proton maximum energy is the function of both laser intensity and pulse duration.

TL;DR: In this paper , the authors demonstrate a scheme for enhanced proton acceleration from near-critical density targets by splitting a laser pulse into a linearly and a circularly polarized laser pulse.
Proton acceleration from overdense plasma target interacting with shaped laser pulses in the presence of preplasmas
TL;DR: In this article, the effect of pulse asymmetry in the presence of preplasma enhances the peak energy of the protons for the case of fast leading edge pulse, which can be used as a tuning parameter to improve the proton beam quality in the TNSA scheme.
