Widely tunable sub-30 fs ultraviolet pulses by chirped sum frequency mixing

Kozma, Ida Z.; Baum, P.; Lochbrunner, Stefan und Riedle, Eberhard (November 2003): Widely tunable sub-30 fs ultraviolet pulses by chirped sum frequency mixing. In: Optics Express, Bd. 11, Nr. 23: S. 3110-3115

Abstract

A novel scheme for the generation of UV pulses in the 295 450 nm range is presented. Sum frequency mixing of the chirped visible pulses from a noncollinear optical parametric amplifier with deliberately chirped pulses from the Ti: sapphire amplifier ensures efficient energy conversion and easy tunability. Pulse energies as high as 5.5 muJ at 295 nm, and > 2 muJ in most of the tuning range are obtained with highly symmetric and smooth spectra. They are compressed to sub-30 fs throughout the entire tuning range (20 fs at 348 nm) with a newly designed prism compressor. (C) 2003 Optical Society of America.
