(a) Correlation plot between the integrated intensity of the ROI and the incident X-ray pulse energy, with red: only X-ray [focus diameter: 15 µm (FWHM)]; black: X-ray and optical laser (wavelength: 800 nm) at negative delay (−1 ps); and blue: X-ray and optical laser (wavelength: 800 nm) at positive delay (+1 ps). (b) Time delay and intensity dependences of the optical laser transmission (wavelength: 800 nm). |
