High-power laser pulse compression for optimized high-harmonic generation in short hollow fibers
High-power laser pulse compression for optimized high-harmonic generation in short hollow fibers
 
  High-harmonic generation (HHG) driven by high-power femtosecond lasers is a promising route towards tabletop sources of coherent radiation at extreme ultraviolet (XUV) and soft Xray wavelengths. In order to maximize conversion efficiency and to obtain attosecond pulse lengths of the harmonics, pump pulse lengths down to the few-cycle regime are required. Traditionally, this has been achieved by nonlinear spectral broadening in gases and subsequent dispersion compression or by self-compression in laser-induced filaments. Here we investigate an alternative method that is simpler to implement experimentally, based on multimode non-linear propagation effects in short, centimeter-length, gas-filled hollow fibers operating in the high-ionization regime.

          Abstract
          High-harmonic generation (HHG) driven by high-power femtosecond lasers is a promising route towards tabletop sources of coherent radiation at extreme ultraviolet (XUV) and soft Xray wavelengths. In order to maximize conversion efficiency and to obtain attosecond pulse lengths of the harmonics, pump pulse lengths down to the few-cycle regime are required. Traditionally, this has been achieved by nonlinear spectral broadening in gases and subsequent dispersion compression or by self-compression in laser-induced filaments. Here we investigate an alternative method that is simpler to implement experimentally, based on multimode non-linear propagation effects in short, centimeter-length, gas-filled hollow fibers operating in the high-ionization regime.
