Cascaded quadratic soliton compression of high-power femtosecond fiber lasers in Lithium Niobate crystals

摘要

The output of a high-power femtosecond fiber laser is typically 300 fs with a wavelength around $lambda=1030-1060$ nm. Our numerical simulations show that cascaded quadratic soliton compression in bulk LiNbO$_3$ can compress such pulses to below 100 fs.
