High-energy light pulses that are tunable from 1.1 to 2.6 μm, with a duration as short as 14.5 fs were generated in a type II phase-matching β-BaB<sub>2</sub>O<sub>4</sub> traveling-wave parametric converter pumped by 18-fs pulses obtained from a Ti:sapphire laser with chirped-pulse amplification, followed by a hollow-fiber compressor.
