Abstract

We report a demonstration of laser intensity exceeding 1023 W/cm2 with the CoReLS petawatt laser. After wavefront correction and tight focusing with a two-stage adaptive optics system and an f/1.1 (f=300 mm) off-axis parabolic mirror, we obtained a focal spot of 1.1 μm (FWHM). From the measurement of 80 consecutive laser shots at 0.1 Hz, we achieved a peak intensity of (1.1±0.2)×1023 W/cm2. This achievement will enable us to explore strong-field quantum electrodynamics phenomena.
