We report on femtosecond petawatt laser pulses at 0.1 Hz that combine both Ti:sapphire chirped-pulse amplification (CPA) and optical parametric CPA (OPCPA) techniques. High temporal contrast of 1012 prior to the main pulse of 10 J output energy has b

Spatial and spectral x-ray characterization of the Target Normal Sheath Acceleration regime

Autor: Lowe, HazelFrances

In the high energy, high density plasmas formed by the interaction of an ultra-short pulse laser with a ~100nm-1µm target foil, ions are generated by Target Normal Sheath Acceleration (TNSA). TNSA and specifically the formation of the sheath field o
