“…We also note here that within or beyond the ponderomotive limit, energy gain of GeV magnitude can also be realized in other various regimes, see Refs. [35,44,45]. Note that, in contrast to full-pulse interactions, in half-pulse interactions the initial phase of electrons, i.e., position, is of importance for the energy gain, as shown in Figs.…”

“…In this bubble regime DLA and LWFA are affected mainly by overlapping of laser field with electrons and enough transverse momentum of injected electrons. It has been shown that these conditions are maintained by using a circularly polarized laser pulse instead of linearly polarized one [43]. The laser plasma interaction will efficiently accelerate electrons by applying an external magnetic field [44].…”

The generation of laser driven plasma wake wave has been investigated in hydrogen  pair-ion electron plasma. The consideration of  dynamics of the positive and negative ion pair have been adopted. Inclusion of the ion motion has the effect of modifying the electric field and density profiles of the wake wave. This has been demonstrated by observing the variation of the  electron density and electric field profiles with the change in positive ion/ negative ion concentration. High density spikes and sawtooth like electric field profiles (indication of wave breaking) are observed  to transform into sinusoidal electric field profile and low amplitude density profile  when the positive ion density in the plasma system is kept higher. Furthermore, we observe the variation of  the electric field amplitude of the wake wave with the laser pulse width. This feature is the indication of  the possibility of hybrid acceleration (Direct Laser Acceleration and wake field acceleration)  of accelerated beam. The results are quite relevant in the field Laser plasma interaction field  in experimental physics and also in planetary environment.

“…Practically, it is fulfilled when τ 0 ≲ 1.3λ/c, see the results for τ 0 = 3 fs. In the same manner, single electron attobunch can be generated employing different configurations of the laser pulse interaction with the overdense target [40,41]. • In the case of longer pulses, another option is controlling the laser intensity.…”

Ultrahigh-intensity laser-plasma physics provides unique light and particle beams as well as novel physical phenomena. A recently available regime is based on the interaction between a relativistic intensity few-cycle laser pulse and a sub-wavelength-sized mass-limited plasma target. Here, we investigate the generation of electron bunches under these extreme conditions by means of particle-in-cell simulations. In a first step, up to all electrons are expelled from the nanodroplet and gain relativistic energy from time-dependent local field enhancement at the surface. After this ejection, the electrons are further accelerated as they copropagate with the laser pulse. As a result, a few, or under specific conditions isolated, pC-class relativistic attosecond electron bunches are generated with laser pulse parameters feasible at state-of-the-art laser facilities. This is particularly interesting for some applications, such as generation of attosecond x-ray pulses via Thomson backscattering.
