By using the strong L-lines emitted from Cu plasma as pulse X-ray source produced by irradiating Cu target with a 1.06 μm pulse laser of the LF-11 laser facility,the reponses of X-ray film Kodak AA-5, Kodak SWR and UFSH-O were calibrated.Calibrated responses with the pulse X-ray source were compared with that with continuum X-ray source (fluoresent source exciteed by protons). These results showed the reciprocity failure. The response to continuum X-ray source is not suitable for the diagnostics in laser-induced plasma.
