In the Kansai Photon Science Institute of Japan Atomic Energy Agency (JAEA), spatially full coherent X-ray laser beam at wavelength of 13.9 nm has been demonstrated by means of oscillator-amplifier scheme. We have already started application researched using the 13.9-nm laser, however the shot rate of the present system, 1 shot per 20 minutes, is not sufficient. The shot rate is limited by cooling time of the rod amplifier. We have developed new driver laser system (TOPAZ: Twin OPtical Amplifiers using Zigzag slab) for pumping the X-ray lasers at 0.1-Hz repetition rate at JAEA. The laser system consists of Ti:Sapphire oscillator ( = 1053 nm), pulse stretcher, OPCPA, prepulse generator, flash lamp pumped zigzag slab Nd:glass amplifiers, pulse compressor, and line focusing system.
