Abstract

To realize the ultrahigh intensity over 10^23 W/cm^2, we carried out the wavefront correction and tight focusing of the CoReLS petawatt laser. By the wavefront correction and tight focusing of the CoReLS petawatt laser with two-stage adaptive optics systems and an f/1.1 (f=300 mm) off-axis parabolic mirror, we obtained a near-diffraction-limited focal spot. The measured peak intensity was (1.1±0.1)×10^23 W/cm2, the first realization of the laser intensity over 10^23 W/cm^2. With the PW laser of intensity over 10^23 W/cm^2, we plan to explore strong field QED phenomena and proton/ion acceleration dominated by the RPA mechanism.
