    The authors' multi-dimensional particle-in-cell simulations demonstrate that a 10-GeV electron bunch with 20-pC charge can be obtained by the two-color dual-stage LWFA using total input laser power of 0.6 PW. We propose an all-optical dual-stage laser wakefield acceleration (LWFA), staged with co-propagating two-color laser pulses in a plasma medium, to enhance the electron bunch energy. After ...

    by two independent laser pulses focused separately to two plasma media 15,18,19. All these methods for dual-staged LWFA require two plasma media with Luo et al .19 showing multi stage coupling of ...

    From this figure, as the laser pulse propagates into the plasma medium, the potential and, thus, the longitudinal sawtooth wakefield begin to excite simultaneously. 2,3 Using Eqs. -, we obtain the energy gain and the electron density distribution behind the pulse.The profiles of these characteristics as a function of k p ζ are plotted in Fig. 2.The ponderomotive force changes the electron ...

    In this all optical dual-stage LWFA, the electrons can gain 3 times higher energy as compared to the energy gain from the single stage LWFA driven by a single-color laser pulse with equivalent energy.

We propose an all-optical dual-stage laser wakefield acceleration (LWFA), staged with co-propagating two-color laser pulses in a plasma medium, to enhance the electron bunch energy.

    A proof-of-principle experiment on staged all-optical laser wakefield acceleration was performed at the Naval Research Laboratory. Electrons with < 1 MeV energy created by the interaction of a 2 TW laser beam with a nitrogen gas jet were injected and accelerated to more than 20 MeV in a plasma wakefield generated by a 10 TW laser beam in a helium gas jet. . The energy gain occurred in a narrow ...

    We propose an all-optical dual-stage laser wakefield acceleration (LWFA), staged with co-propagating two-color laser pulses in a plasma medium, to enhance the electron bunch energy. After the depletion of the leading fundamental laser pulse that initiates self-injection and sets up the first stage p …
