Description
We report the experimental demonstration of double-layer foam targets (DLFTs), consisting of ultra-low-density carbon foam deposited on thin aluminum foils, for enhanced laser-driven proton acceleration in the TNSA regime. Compared to bare aluminum targets, DLFTs exhibit improved laser absorption and modified preplasma formation, resulting in increased proton cut-off energy and particle flux. The targets were tested over a wide range of laser intensities and contrast conditions, spanning from ~10^13 W·cm⁻² up to ~10^21 W·cm⁻², with and without nanosecond-scale prepulses preceding the main pulse, demonstrating their robustness and effectiveness across multiple experimental configurations.
