We are now upgrading our Ti:sapphire laser system with chirped pulse amplification (CPA) at the Kansai Photon Science Institute, Japan Atomic Energy Agency. The laser system will be able to provide PW level on target at the repetition rate of 0.1 Hz. The challenge is to achieve the focused intensity of 10 $^{22}$ W/cm with a f/1.4 optic employing two deformable mirrors. Two target chambers are prepared mainly for short-focus (f/1.4) with multiple vacuum ports and for long-focus f/10 or f/20. Applications of such intense lasers are also presented. They are relativistic flying mirrors, high order harmonics generation, ion acceleration, and ray flash, etc.
