Acquiring 1053 nm femtosecond laser emission by optical parametric amplification based on supercontinuum white-light injection.
We report a terawatt-Ti:sapphire-laser-pumped high-energy femtosecond optical parametric amplifier (OPA) with supercontinuum white-light injection. Signal pulses with a duration less than 100 fs and energy up to 4 mJ are obtained with large-aperture LiNbO3 crystals. This megajoule-class femtosecond OPA at 1053 nm presents a feasible alternative to optical parametric chirped-pulse amplification and is ready to be applied to petawatt lasers.
