We report on the complete temporal characterization of ultrashort pulses, generated by resonant dispersive wave emission in gas-filled hollow-capillary fibers, with energy microjoule range and continuously tunable from deep-ultraviolet to ultraviolet. Temporal such ultrabroad particularly challenging 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, 250 nm 350 nm, a minimum pulse...
An erratum is presented to include the correct upper horizontal axis in Fig. 3 our published manuscript [“Direct temporal characterization of sub-3-fs deep UV pulses generated by resonant dispersive wave emission” Opt. Express 31 , 26854 ( 2023 ). 10.1364/OE.494879
The generation of few-femtoseconds laser pulses in the Deep Ultraviolet (DUV) spectral region (200–300 nm) is crucial for investigation ultrafast electronic dynamics several classes molecules. As prominent examples, both DNA nucleobases [1], as well donor-acceptor systems, relevant optoelectronic applications, readily absorb this range. In context, Resonant Dispersive Wave (RDW) emission gas-filled Hollow Core Fibers (HCF) a novel and efficient way to generate <tex...
