Self-calibrating d-scan: measuring ultrashort laser pulses on-target using an arbitrary pulse compressor
Benjamin Alonso, Iñigo J. Sola, Helder Crespo
In most applications of ultrashort pulse lasers, temporal compressors are used to achieve a desired pulse duration in a target or sample, and precise temporal characterization is i…
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…
Tunable high-harmonic generation by chromatic focusing of few-cycle laser pulses
