CEP-Stable 100 kHz Nonlinearly Compressed YDFA Source for HHG
Résumé
Summary form only given. Over the last years, the interest for high repetition rate (>100kHz) sources used for high harmonic generation (HHG) has been growing up widely. Indeed, increasing laser repetition rate allows, for example, to drastically increase the HHG photon flux. Moreover, additional benefits such as improved statistics and signal-to-noise ratio or a reduced acquisition time are also paramount for low-interaction probability experiments. Using nonlinear compression scheme, Yb-doped fiber amplifiers (YDFA) are now able to provide the performances suitable for HHG-related applications. However, one of the remaining bottleneck of these sources is the lack of carrier-envelope phase (CEP) stabilization. So far, CEP stabilization of ytterbium-doped amplifiers has only been demonstrated for oscillator or low energy systems. We have demonstrated a high energy FCPA operated at 100 kHz showing excellent CEP stability. We believe that power and energy scaling toward > 100 W, > lmJ, with CEP -stabilization is within reach. Together with recently demonstrated ultra -high efficiency nonlinear compression to few cycle pulse duration [6], this new kind of source promises to disrupt applications in attoscience.
