Adak, Amitava, Singh, Prashant Kumar, Lad, Amit D. et al. (6 more authors) (2016) Efficient transport of femtosecond laser-generated fast electrons in a millimeter thick graphite. Applied Physics Letters. 174101. pp. 1-5. ISSN 0003-6951
Abstract
We demonstrate efficient transport of fast electrons generated by ∼1018 W/cm2, 30 fs, 800 nm laser pulses through a millimeter thick polycrystalline graphite. Measurements of hot electron spectra at the front side of the graphite target show enhancement in terms of the electron flux and temperature, while the spectra at the rear confirm the ability of the graphite to transport large electron currents over a macroscopic distance of a millimeter. In addition, protons of keV energies are observed at the rear side of such a macroscopically thick target and attributed to the target-normal-sheath-acceleration mechanism.
