Fig. 1. The damage morphologies of a formvar target under laser irradiation at the intensity of (a) 6×1012 W/cm2 and (b) 1.1×1013 W/cm2. (c) The intensity distribution around the focal spot. (d) A line out of the laser intensity across the focal spot (scattered black circle), the corresponding Gaussian fit (red line), and the exponential fit (green line) of the raw data.

Fig. 2. Diameter of the damaged area with respect to the laser intensity.

Fig. 3. Pulse duration dependence of DTF for formvar (bule diamonds), SiN (green triangles), DLC (black stars), Al (red crosses), a-C (purple squares), and CNT (orange circles).

Fig. 4. The temporal profiles of three ultraintense femtosecond laser pulses from the SULF, CoReLS, and CLAPA facilities, respectively.

Fig. 5. Comparison between DTIs of the tested ultrathin foils and the prepulse intensity.
