This paper reviews the development of a high-contrast high-intensity petawatt-class Ti:sapphire chirped-pulse amplification (CPA) laser for research on high field science. We discuss in detail the design, performance and characterization of the laser. We also describe the on-going upgrade of the laser system and some applications for the laser in relativistic dominated laser-matter interactions.

We present the on-going upgrade of our high intensity laser system (J-KAREN laser system) in JAEA for higher energy and higher repetition rate operation as an invited talk. We discuss the status and implementation of the upgrade, including system design, evaluation of the components in the system, and the expected performance and characterization of the laser.

We report recent progress on the J-KAREN laser upgrade to realize 10$$^{22}$$ W/cm$$^{2}$$ intensity at 0.1 Hz. Our current high-spatiotemporal-quality broadband pulses of over 20 J will be further amplified in the final amplifier.

We present recent progress on the J-KAREN laser upgrade to realize 10$$^{22}$$ W/cm$$^{2}$$ intensity at 0.1 Hz as an invited talk at CLEO-PR 2015. Our current high-spatiotemporal-quality broadband pulse from the front end is amplified in the final amplifier to over 55 J at this moment. We plan to mention the detailed design, performance and the future prospects.
