New driver laser system for the 0.1-Hz x-ray laser is described. The driver laser is based on CPA laser with Nd:glass power amplifier. By using flash lamp pumped zigzag slab amplifier, energy extraction of > 10 J can be obtained at 0.1-Hz operation. Pulse duration of the laser light after pulse compression is 3.6 ps. These energy and duration satisfy a condition for x-ray laser generation.
