Role of surface roughness in hard x-ray emission from femtosecond laser produced copper plasmas

P. P. Rajeev, S. Banerjee, A. S. Sandhu +2

The hard x-ray emission in the energy range of 30-300 keV from copper plasmas produced by 100 fs, 806 nm laser pulses at intensities in the range of 10${}^{15}-10^{16}$ W cm${}^{-2}$ i…
