Furthermore, investigate, both theoretically experimentally, scaling MHz-level repetition rates, when inter-pulse effects cannot neglected.

Many these scientific cases benefit from sources higher average peak powers. Following mode-locked dye titanium-doped sapphire lasers, broadband optical parametric amplifiers have emerged as peak- power ultrashort pulse lasers.

Soliton dynamics can be used to temporally compress laser pulses few fs durations in many different spectral regions. Here we study analytically, numerically and experimentally the scaling of soliton noble gas-filled hollow-core fibers. We identify an optimal parameter region, taking account higher-order dispersion, photoionization, self-focusing, modulational instability. Although for single-shots effects photoionization reduced by using lighter gases, they become increasingly important as repetition rate rises. For same optical nonlinearity, higher pressure longer diffusion times gases considerably enhance long-term ionization, a result pulse-by-pulse buildup refractive index changes. To illustrate counter-intuitive nature these predictions, compressed 250 at 1030 nm 80-cm-long photonic crystal fiber (core radius 15 µm) ∼5 duration argon neon, found that, although neon performed better 1 MHz, stable compression was still possible up 10 MHz.

Tunable ultrashort pulses in the ultraviolet spectral region are great demand for a wide range of applications, including spectroscopy and pump–probe experiments. While laser sources capable producing such exist, they typically very complex. Notably, resonant dispersive-wave (RDW) emission has emerged as simple technique generating pulses. However, required pulse energy used to drive RDW emission, so far, is mostly at microjoule level, requiring complicated expensive pump sources. Here, we present our work on lowering threshold tuneable deep level tens nanojoules. We fabricated record small-core antiresonant fiber with hollow-core diameter just 6 μm. When filled argon, small mode area enables higher-order soliton propagation (220 270 nm) from 36 fs 515 nm lowest reported date (tens nanojoules). This approach will allow use low-cost compact oscillators nonlinear optics gas-filled fibers first time knowledge.
