    Electron-positron cascades in multiple-laser optical traps. Marija Vranic 3,1, ... For electron-positron cascade configurations with linearly polarised lasers A-C displayed in figure 1, the definitions of the different standing waves are given in the appendix. We assume the phase difference between one pair of lasers is the same as the ...

    QED cascades, where the number of electron-positron pairs created in the laser field grows exponentially [16, 17]. The role of the laser in such cascade is tw ofold: it accelerates the electrons and
  3. We present an analytical and numerical study of multiple-laser QED cascades induced with linearly polarised laser pulses. We analyse different polarisation orientations and propose a configuration that maximises the cascade multiplicity and favours the laser absorption. We generalise the analytical estimate for the cascade growth rate previously calculated in the field of two colliding ...

  4. Electron - positron cascades in multiple-laser optical traps 4 Figure 1. Setup: A thin cryogenic ice target is placed in the focus of four lasers. A pair of lasers propagates along the x-axis, and another pair along y-axis. In Setup A, the lasers are all polarised perpendicularly to the x-y plane of motion (the illustrations

    The estimate is verified by a comprehensive numerical study of four-laser QED cascades across a range of different laser intensities with QED PIC module of OSIRIS. We show that by using four linearly polarised 30 fs laser pulses, one can convert more than 50% of the total energy to gamma-rays at laser intensity .

    the conservation of the electron generalized momentum, which gives the component of the electron momentum parallel to the laser electric field. One can see that the quantum effects are maximized for an electron/positron or a photon counter-propagating with the EM wave. In the ultra-relativistic limit, γ ≫ 1: χ↑↓ e = 2γ E ES, χ↑↓ ...

We show that by using four linearly polarised 30 fs laser pulses, one can convert more than 50 % of the total energy to gamma-rays already at laser intensity I≃ 10 24 W/c m 2 .
