We report the generation of the second to the sixth harmonics of a fundamental frequency covering two and a half octaves in a multiply-periodically poled lithium tantalate crystal by cascaded quasi-phase-matched frequency mixing. A frequency comb that is composed of these harmonics will permit the synthesis of a train of periodic subcycle subfemtosecond pulses in a compact setting. (C) 2009 Optical Society of America

Up to seven laser harmonics covering more than two octaves in frequency have been generated efficiently in a single PPLT crystal. permitting the syntehsis of 1.5 femtosecond pulses in a stable and compact setting
