G. Cerullo et al., GENERATION OF 11 FS PULSES TUNABLE ACROSS THE VISIBLE BY OPTICAL PARAMETRIC AMPLIFICATION, Applied physics letters, 71(25), 1997, pp. 3616-3618
We have generated pulses with 11 fs duration, tunable between 500 and
700 nm, using a noncollinear beta-barium borate optical parametric amp
lifier pumped by the second harmonic of a Ti:sapphire laser. (C) 1997
