We have developed a chirped pulse amplification laser with zigzag slab Nd:glass power amplifiers which provides two synchronized beams with energy of $$sim$$10 J and duration of a few ps at 0.1-Hz repetition-rate. Using this laser as a driver, fully spatial coherent X-ray laser at a wavelength of 13.9 nm is generated at 0.1 Hz. Typical energy, beam divergence and duration of the X-ray laser are $$sim$$1 $$mu$$J, 0.5 mrad and 7 ps, respectively. Hence, a quite high peak brilliance is achieved. Using this X-ray laser, various application researches have been started.
