Isolated attosecond pulses by self-compression in short gas-filled fibers
Isolated attosecond pulses by self-compression in short gas-filled fibers
The intense few-cycle driving fields used to produce isolated attosecond pulses via high harmonic generation (HHG) [1] are typically delivered from conventional hollow fiber compressors. However, it has been suggested that individual attosecond pulses may be realized in low-pressure regions at the output of self-compressed filaments [2]. We follow a similar approach in an alternative geometry and present modelling of an elegant source of isolated attosecond pulses driven by a 40 fs near infrared (NIR) laser field. Here, ionization-induced self-compression and HHG happen in-situ within a short (40 mm) gas-filled fiber, and single 350 as pulses at a central wavelength of 13.5 nm are predicted at its exit.

Abstract
The intense few-cycle driving fields used to produce isolated attosecond pulses via high harmonic generation (HHG) [1] are typically delivered from conventional hollow fiber compressors. However, it has been suggested that individual attosecond pulses may be realized in low-pressure regions at the output of self-compressed filaments [2]. We follow a similar approach in an alternative geometry and present modelling of an elegant source of isolated attosecond pulses driven by a 40 fs near infrared (NIR) laser field. Here, ionization-induced self-compression and HHG happen in-situ within a short (40 mm) gas-filled fiber, and single 350 as pulses at a central wavelength of 13.5 nm are predicted at its exit.
