Simultaneous X-ray and optical shadowgraphy of cavities heated by 0.44µm laser light
Gold cavity targets were irradiated with 0.44 µm laser light at intensities up to 2.6 x 1.0 E13 W/cm2. The outward motion of the cavity wall was investigated by simultaneous optical and X-ray shadowgraphy. The wall motion was attributed to the pressure generated by an ablative heat wave, driven by the soft X-rays in the cavity. The observed transparency of the cavities for the X-rays used for shadowgraphy allowed the determination of the density profile of the cavity wall which decayed possibly due to fragmentation.
