Ultrafast laser pulse characterization by THG d-scan using optically enhanced graphene coatings
Tiago Gomes, Miguel Canhota, Bohdan Kulyk +6
We have successfully functionalized 5 layers of TCVD-grown graphene by photoassisted transfer hydrogenation reaction with formic acid, in order to increase its nonlinear optical re…
Temporal characterization of broadband femtosecond laser pulses by third-harmonic dispersion scan with ptychographic retrieval
Tiago Gomes, Miguel Canhota, Helder Crespo
We present a new variant of dispersion scan (d-scan) based on surface third-harmonic generation (STHG) and a ptychographic algorithm taylored for full retrieval (amplitude and phas…
Characterizing ultrashort laser pulses with second harmonic dispersion scans
Ivan Sytcevich, Chen Guo, Sara Mikaelsson +9
The dispersion scan (d-scan) technique has emerged as a simple-to-implement characterization method for ultrashort laser pulses. D-scan traces are intuitive to interpret and retrie…
Single-shot d-scan technique for ultrashort laser pulse characterization using transverse second-harmonic generation in random nonlinear crystals
Francisco J. Salgado-Remacha, Benjamín Alonso, Helder Crespo +10
We demonstrate a novel dispersion-scan (d-scan) scheme for single-shot temporal characterization of ultrashort laser pulses. The novelty of this method relies on the use of a highl…
Compression of CEP-stable multi-mJ laser pulses down to 4 fs in long hollow fibers
Frederik Bohle, Martin Kretschmar, Aurelie Jullien +8
Carrier envelope phase stable 4 fs near-IR pulses with 3 mJ energy were generated by spectral broadening of circularly polarized 8 mJ pulses in a differentially pumped 2 m long com…
Universal route to optimal few- to single-cycle pulse generation in hollow-core fiber compressors
Enrique Conejero Jarque, Julio San Roman, Francisco Silva +6
Gas-filled hollow-core fiber (HCF) pulse post-compressors generating few- to single-cycle pulses are a key enabling tool for attosecond science and ultrafast spectroscopy. Achievin…
