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 $3\times 10^{13}$ W/cm2. X-ray energy is measured using an X-ray charge-coupled device. The obtained spectrum consists of strong Kα and Kβ 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/$4\pi\mathrm{sr}$/pulse.
