The relativistic flying mirror concept has several interesting features for generating short wavelength, coherent, ultrashort electromagnetic radiation. The experiment of the relativistic flying mirror was conducted in a head-on collision setup using J-KAREN laser (400 mJ, 30 fs). Initially 800 nm laser pulses were converted to the extreme ultraviolet region (several tens of nm). The source size of the radiation was characterized to 7.1m with an imaging system composed of a spherical mirror and CCD.
