High-energy light pulses that are tunable from 1.1 to 2.6 mu m, with a
duration as short as 14.5 fs were generated in a type II phase-matchi
ng beta-BaB2O4 traveling-wave parametric converter pumped by 18-fs pul
ses obtained from a Ti:sapphire laser with chirped-pulse amplification
, followed by a hollow-fiber compressor. (C) 1998 Optical Society of A
