Abstract
We report on the design and characterisation of the plasma mirror system installed on the J-KAREN-P laser at the National Institutes for Quantum Science and Technology, Kansai Photon Science Institute. The reflectivity of the single plasma mirror system exceeded 80%. Additionally, the temporal contrast was improved by two orders of magnitude at 1 ps before the main pulse. Furthermore, the laser near field spatial distribution after the plasma mirror was kept constant at plasma mirror fluence <100 kJ/cm2. We also present the results of investigating the difference and the fluctuation in energy, pulse width, and pointing stability with and without the plasma mirror system.
