We have been developing a pulsed-laser storage technique in a super-cavity for acompact x-ray sources. The pulsed-laser super-cavity enables to make high peak power andsmall waist laser at the collision point with the electron beam. Recently, using 357 MHzmode-locked Nd:VAN laser pulses which stacked in a super-cavity scattered off a multi-bunchelectron beam, we obtained a multi-pulse xrays through the laser-Compton scattering. Then,we performed a X-ray imaging via laser-Compton X-ray. The images have edge enhancement byrefraction contrast because the X-ray source spot size was small enough. This is one of theevidences that laser-Compton X-ray is high quality. Our laser-Compton experimental setup,the results of Xray imaging and future prospective will be presented at the conference.
