The effect of rotational Raman response on ultra-flat supercontinuum generation in gas-filled hollow-core photonic crystal fibers
Mohammed Sabbah, Federico Belli, Christian Brahms +1
We experimentally and numerically investigate flat supercontinuum generation in gas-filled anti-resonant guiding hollow-core photonic crystal fiber. By comparing results obtained w…
On-target delivery of intense ultrafast laser pulses through hollow-core anti-resonant fibers
Athanasios Lekosiotis, Federico Belli, Christian Brahms +5
We report the flexible on-target delivery of 800 nm wavelength, 5 GW peak power, 40 fs duration laser pulses through an evacuated and tightly coiled 10 m long hollow-core nested an…
Dispersion-tuning of nonlinear optical pulse dynamics in gas-filled hollow capillary fibers
Teodora Grigorova, Christian Brahms, Federico Belli +1
We experimentally investigate the nonlinear optical pulse dynamics of ultrashort laser pulses propagating in gas-filled hollow capillary fibers in different dispersion regimes, whi…
Generation and characterization of frequency tuneable sub-15 fs pulses in a gas-filled hollow-core fiber pumped by a Yb:KGW laser
Mohammed Sabbah, Federico Belli, Christian Brahms +3
We investigate soliton self-compression and photoionization effects in an argon-filled antiresonant hollow-core photonic crystal fiber pumped with a commercial Yb:KGW laser. Before…
Efficient and compact source of tuneable ultrafast deep ultraviolet laser pulses at 50 kHz repetition rate
Christian Brahms, John C. Travers
Deep ultraviolet (DUV) laser pulses with tuneable wavelength and very short duration are a key enabling technology for next-generation technology and ultrafast science. Their gener…
Soliton self-compression and resonant dispersive wave emission in higher-order modes of a hollow capillary fibre
Christian Brahms, John C. Travers
We investigate soliton self-compression and ultraviolet resonant dispersive wave emission in the higher-order modes of a gas-filled hollow capillary fibre. Our simple analytical sc…
