We generated synchronized sub-200-fs pulses between 3 and 4.4{mu}m at a 1-kHz repetition rate by pumping a KNbO{sub 3} optical parametric amplifier with a femtosecond Ti:sapphire regenerative amplifier and seeding it by narrow-band quasi-cw radiation. Output idler energies as high as 7{mu}J at 4{mu}m are reported from this extremely simple single-stage device, which correspond to amplification factors as high as 3{times}10{sup 5} and a conversion efficiency of 15. {copyright} {ital 1996 Optical Society of America.}
