A six-octave optical frequency comb from a scalable few-cycle erbium fibre laser
Ultralow-noise erbium:fibre comb technology allows the generation of a comb spanning six octaves, from the ultraviolet (350 nm) to the mid-infrared (22,500 nm), with a resolving power of 1010 across 0.86 PHz of bandwidth.

Seven-octave high-brightness and carrier-envelope-phase-stable light source
Using a gas-filled anti-resonant-reflection photonic-crystal fibre, a high-brightness table-top source of coherent carrier-envelope-phase-stable waveforms is demonstrated across seven octaves (340 nm to 40,000 nm) with ultraviolet peak powers up to 2.5 MW and terahertz peak powers of 1.8 MW, without the need for changing nonlinear crystals.

High-energy pulse self-compression and ultraviolet generation through soliton dynamics in hollow capillary fibres
Optical soliton dynamics in large-core hollow capillary fibres is demonstrated. The findings enable the scaling of soliton effects by several orders of magnitude to the multi-millijoule energy and terawatt peak power levels, and open up opportunities for new-generation table-top light sources for ultrafast strong-field physics and advanced spectroscopy.

Relativistic single-cycle tunable infrared pulses generated from a tailored plasma density structure
A scheme for generating intense single-cycle pulses in the 5–14 μm wavelength range is proposed. The generation mechanism is described by photon frequency downshifting of an off-the-shelf Ti:sapphire laser in a tailored plasma density structure.

Polarization control of isolated high-harmonic pulses
Circularly polarized isolated extreme-ultraviolet pulses are generated by exploiting non-collinear high- harmonic generation driven by two counter-rotating few-cycle laser beams. The numerical simulation predicts a linear chirp of 330 attoseconds.

Mid-infrared frequency comb via coherent dispersive wave generation in silicon nitride nanophotonic waveguides
The direct generation of mid-infrared optical frequency combs in the region 2.5–4.0 μm from a 1.55-μm conventional and compact erbium-fibre-based femtosecond laser is demonstrated via coherent dispersive wave generation in silicon nitride nanophotonic waveguides.

Fibre multi-wave mixing combs reveal the broken symmetry of Fermi–Pasta–Ulam recurrence
The Fermi–Pasta–Ulam recurrence process—the recovery of the initial state of a nonlinear system after a certain time—is observed for the first time in a low-loss optical fibre by building a multi-channel, vector optical-time-domain reflectometer.

Integrating solids and gases for attosecond pulse generation
Isolated attosecond pulses (IAPs) in the extreme-ultraviolet range are generated by the interaction of half-cycle mid-infrared pulses with gas (Xe, Kr or Ar) and solid media (quartz). The energy of the IAPs is optically tunable over an octave.
