Pair production can be triggered by high-intensity lasers via the Breit–Wheeler process.
However, the straightforward laser–laser colliding for copious numbers of pair creation …

Although several laser–plasma-based methods have been proposed for generating
energetic electrons, positrons and γ-photons, manipulation of their microstructures is still …

High-energy positrons and bright γ-ray sources are of great importance both in fundamental
research and for practical applications. However, collimated GeV electron–positron pair jets …

When a high-contrast ultra-relativistic (> 10 20 W/cm 2) laser beam enters a micro-sized
plasma waveguide, the pulse energy is coupled into waveguide modes, which significantly …

We report a proposal to generate an ultra-bright, well-collimated, GeV gamma-ray source in
the quantum electrodynamics regime. An ultra-intense laser is used to excite a bubble-like …

With two-dimensional quantum electrodynamics (QED) particle-in-cell simulations, a dense
electron–positron (e− e+) pair generation from laser-solid interactions is demonstrated …

With the continuous development of technology, the laser power has exceeded 10 PW. The
interaction between such intense laser pulse and matter enters the near quantum …
