Probing the vacuum structure by combinations of high-intensity laser technologies

The quantum vacuum is a rich object which may contain known and unknown ingredients such as dark matter and dark energy. Probing the vacuum to date has been limited to either the macroscopic scale with astronomical observations or the microscopic space-time points at highenergy particle collisions. With high-intensity lasers, however, we may be able to probe different aspects of the quantumvacuumwith different space-time scales. We will present what we can potentially discuss with laser-laser and energetic particles-laser interactions in the vacuum by combining cutting-edge laser technologies.
