“…We mention that in addition to the rather clean temporal shape on the femtosecond time scale, the present approach is free of superfluorescence background as was reported in case of OPCPA. 5 When the seed is blocked in the OPA, no light is observed at the output of the fiber. FIG.…”

“…The key ingredient for reducing the pulse duration to few optical cycles at high power levels lies in additional spectral broadening through either (i) nonlinear propagation in hollow-core-fiber (HCF) [2] and laser-induced (co-)filaments [3][4][5] or (ii) ultrabroadband optical parametric amplification (OPA) [6] and OPCPA [7]. However, the main challenge remains in controlling the spectral phase of the ultrabroadband spectrum.…”

Mechanism of hollow-core-fiber infrared-supercontinuum compression with bulk material

We numerically investigate the pulse compression mechanism in the infrared spectral range based on the successive action of nonlinear pulse propagation in a hollow-core fiber followed by linear propagation through bulk material. We found an excellent agreement of simulated pulse properties with experimental results at 1.8 µm in the two-optical-cycle regime close to the Fourier limit. In particular, the spectral phase asymmetry attributable to self-steepening combined with self-phase modulation is a necessary prerequisite for subsequent compensation by the phase introduced by glass material in the anomalous dispersion regime. The excellent agreement of the model enabled simulating pressure and wavelength tunability of sub-two cycles in the range from 1.5 to 4 µm with this cost-efficient and robust approach.

“…The generation of isolated attosecond pulses in the water window has an extremely vital significance for studying the ultrafast electronic dynamics of biological samples in water. With the rapid development in ultrafast laser technology, the intense ultrafast laser sources in the midinfrared region have been achieved [7][8][9][10] and have been employed experimentally [2,11], which makes it possible to realize the attosecond pulse generation in the water window. Several approaches have so far been proposed to achieve single attosecond pulses in this spectral region, including the detuned midinfrared two-color scheme [12], midinfrared polarization gating modulated by a weaker linearly polarized pulse [13,14], and the double optical gating with very high intensity [15].…”

A scheme is proposed to generate isolated attosecond pulses in the water window driven by a multicycle 2400-nm midinfrared laser field with moderate intensity interacting with H 2 + molecules. Single attosecond pulses are achieved due to the charge resonance-enhanced ionization and nuclear motion by the numerical solutions of a non-Born-Oppenheimer time-dependent Schrödinger equation. Thus, the single attosecond pulse generation provides insight into the nuclear dynamics.
