Title: Post-compression of high-energy femtosecond pulses using gas ionization
Author(s): Dutin, C. Fourcade; Dubrouil, A.; Petit, S.; Mevel, E.; Constant, E.; Descamps, D.
Abstract: We present a new optical post-compression technique designed for high-energy ultrashort pulses. A large spectral broadening is achieved through rapid ionization of helium by an intense pulse (> 1015 W/cm2) propagating in a capillary filled with low-pressure helium. The blueshifted pulses are re-compressed with chirped mirrors and silica plates. From a terawatt Ti:sapphire laser chain providing pulses of 40 fs, 70 mJ, we demonstrate the compression of pulses down to 11.4 fs (FWHM) with a total output energy of 13.7 mJ.
