Ultrafast soliton-driven light sources based on gas-filled hollow-fibre nonlinear optics

Soliton-driven frequency conversion provides an exceptionally versatile source of tuneable pulses for ultrafast science. A simple experimental setup using gas-filled hollow-fibres can continuously tune few-femtosecond pulses from the vacuum ultraviolet (around 100 nm) to the near infrared (750 nm), with high efficiency. This technique can be scaled in repetition rate: so far we have reached 50 kHz (limited by our pump laser). It can also produce circularly polarised ultraviolet pulses. Furthermore, soliton self-compression in the same system can be harnessed to produce terawatt-scale sub-cycle pulses in the infrared spectral region.

We present a new technique for asymmetric spectral broadening of high-peak power pulses, which relies on the continuous red-shift provided by rotational, Stimulated Raman Scattering over the long propagation distance in a nitrogen-filled capillary. As a result, pulses can be compressed with a net shift of their central wavelength in the vicinity of their fundamental with high energy efficiency.

Potential applications include high harmonic generation with extended cut-off, frequency difference generation in the 5-9µm range, and filamentation-induced optical path cleaning for telecommunication in the atmosphere.

We report on a nonlinear compression down to 20 fs in air-filled HCPCF. Novel spectral-temporal dynamic is observed and analysed. The results represent a promising pathway for strong and stable compression of current commercial ultra-short-pulse lasers.

We demonstrate the generation of an octave-spanning supercontinuum from 800 nm to 2800 nm in a tellurite multimode graded-index fiber. Our results show signatures of beam self-cleaning opening the way towards high-power supercontinuum light sources in the mid-infrared.

Towards advanced near-infrared spectroscopy at megahertz repetition rates

We report on the efficient external pulse compression of 255 fs, 20 μJ, 2 MHz pulses of a Yb:YAG amplifier to 6.7 fs in two gas-filled photonic crystal fiber; and their broadband down conversion to 2 μm via intra-pulse difference frequency generation. The synchronized, high power, ultrashort pulses, with octave-separated centre frequencies are ideal for advanced near-infrared spectroscopy.
