Schriever, Christian, Lochbrunner, Stefan, Krok, Patrizia and Riedle, Eberhard (January 2008): Tunable pulses from below 300 to 970nm with durations down to 14fs based on a 2MHz ytterbium-doped fiber system. In: Optics Letters, Vol. 33, No. 2: pp. 192-194

Abstract

A noncollinearly phase-matched optical parametric amplifier pumped by a commercial 2 MHz fiber laser is presented and discussed. The pump system allows the direct generation of a seed continuum from a sapphire plate. Clean pulses with up to 860 nJ energy and down to 14 fs pulse length can be obtained over a fundamental tuning range from 620 to 970 nm. Conversion by second- and third-harmonic generation as well as sum frequency mixing results in an extended tuning range down to well below 300 nm. (c) 2008 Optical Society of America.
