Generation of Few Cycle Femtosecond Pulses via Supercontinuum in a Gas-Filled Hollow-Core Fiber
The interaction of intense short nanoand picosecond laser pulses with plasma leads to reach variety of important applications, including time-resolved laser induced breakdown spectroscopy LIBS (Walid Tawfik et al., 2007), soft x-ray lasers (X. F. Li et al., 1989), and laser-driven accelerators (W. P. Leemans et al., 1989). In most cases the useful output whether it be photons or accelerated par...
متن کاملEnergy-scalable temporal cleaning device for femtosecond laser pulses based on cross-polarized wave generation.
We report on a compact energy-scalable device for generating high-fidelity femtosecond laser pulses based on spatial filtering through a hollow-core fiber followed by a nonlinear crystal for cross-polarized wave (XPW) generation. This versatile device is suited for temporal pulse cleaning over a wide range of input energies (from 0.1 to >10 mJ) and is successfully qualified on different ultrafa...
متن کاملGeneration of isolated attosecond pulses with 20 to 28 femtosecond lasers.
Isolated attosecond pulses are powerful tools for exploring electron dynamics in matter. So far, such extreme ultraviolet pulses have only been generated using high power, few-cycle lasers, which are very difficult to construct and operate. We propose and demonstrate a technique called generalized double optical gating for generating isolated attosecond pulses with 20 fs lasers from a hollow-co...
متن کاملParametric amplification of attosecond pulse trains at 11 nm
We report the first experimental demonstration of the parametric amplification of attosecond pulse trains at around 11 nm. The helium amplifier is driven by intense laser pulses and seeded by high-order harmonics pulses generated in a neon gas jet. Our measurements suggest that amplification takes place only if the seed pulse-trains are perfectly synchronized in time with the driving laser fiel...
متن کاملGeneration and characterization of tunable mid-infrared femtosecond pulses
In this Chapter we describe the design of an optical parametric amplifier that allows the generation of infrared laser pulses suitable for ultrafast nonlinear spectroscopy on the OH-stretching mode of water molecules. Mid-infrared femtosecond pulses, tunable in the range of 2800-3800 cm with sub-100 fs duration and ~15 μJ energy are produced by an optical parametric amplifier driven at 1 kHz by...
