We investigate high quality laser proton acceleration with three dimensional particle-in-cell simulations for oblique incidence of the laser pulse on a double-layer target. The double-layer target is composed of a high-Z ion layer coated by a thin and narrow hydrogen patch. The highest proton energy gain is achieved at a certain incidence angle at which the fast proton maximum energy is much grater than the case of normal incidence. The fast protons form a tilted bunch which propagates at some angle with the respect to the normal of the target surface, as determined by the proton energy and the incidence angle.

We are developing plasma X-ray lasers pumped by ultra-short pulse lasers and have concentrated our efforts on developing a silver X-ray laser (13.9 nm) with spatially full coherence and application research using a highly coherent X-ray laser. Recently, we have developed a new pumping laser system, which is a CPA laser consisting of an OPCPA pre-amplifier and zigzag-slab type glass amplifiers. For the purpose of further application experiments, 0.1-Hz operation of the driver laser and the X-ray laser at a wavelength of 13.9 nm were succeeded.
