Abstract

Hard X-ray pulses are generated by focusing a picosecond laser beam (25-ps, 1064 nm) on a copper target in air at an intensity of 3×10¹³ W/cm². X-ray energy is measured using an X-ray charge-coupled device. The obtained spectrum consists of strong K_α and K_β emissions and a weak continuum at an energy range of 4–10 keV. The photon numbers of the hard X-rays (4–10 keV) were estimated to be approximately 4000 photons/4πsr/pulse.
