This article reports on the complete temporal characterization of ultrashort pulses generated by resonant dispersive wave emission in gas-filled hollow-capillary fibers. The energy of these pulses ranges from deep-ultraviolet to ultraviolet and they are continuously tunable. Temporal characterization of these ultrabroad pulses, which is particularly challenging in this spectral region, was achieved using an all-in-vacuum setup for self-diffraction frequency resolved optical gating (SD-FROG). Sub-3-fs pulses were measured, tunable from 250 nm to 350 nm, with a minimum pulse duration of 2.4 ± 0.1 fs.
We report on the complete temporal characterization of ultrashort pulses, generated by resonant dispersive wave emission in gas-filled hollow-capillary fibers, with energy in the microjoule range and continuously tunable from the deep-ultraviolet to the ultraviolet. Temporal characterization of such ultrabroad pulses, particularly challenging in this spectral region, was performed using an all-in-vacuum setup for self-diffraction frequency resolved optical gating (SD-FROG). Sub-3-fs pulses were measured, tunable from 250 nm to 350 nm, with a minimum pulse duration of 2.4 & PLUSMN; 0.1 fs. & COPY; 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
