中文摘要	we found reversible dark-center diffraction of the transmitted probe beam passing through the chromium film. which is induced by the pump femtosecond laser. the dark-center diffraction of i he transmitted probe beam appears and disappears with and without the pump beam. a view of diffractive optics with binary phase plate is put forward, which explains the reversible dark-center diffractive optical phenomenon. the pre-ablated hole on the metal film can be regarded as a uniform light filed without phase modulation, the surrounding circular part around the pre-ablated hole can be regarded as "phase modulated". therefore, this diffraction optic view might be helpful for us to understand the phase change of the metal film introduced by the femtosecond laser pulse.
