  • 2-μm wavelength, high-energy Ho:YLF chirped-pulse amplifier for mid-infrared OPCPA 

    Hemmer, M.; Sánchez, D.; Jelínek, M.; Smirnov, Vadim; Jelinkova, H.; Kubeček, V.; Biegert, Jens (OSA, 2015-02-02)
    Article
    Open Access
    A 2-μm wavelength laser delivering up to 39-mJ energy, ∼10 ps duration pulses at 100-Hz repetition rate is reported. The system relies on chirped pulse amplification (CPA): a modelocked Er:Tm:Ho fiber-seeder is followed ...
  • Broadband mid-IR frequency comb with CSP and AGS from a Er,Tm:Ho fiber laser 

    Sánchez, D.; Hemmer, M.; Baudisch, M.; Zawilski, K.; Schunemann, P.; Hoogland, H.; Holzwarth, R.; Biegert, Jens (OSA, 2014-12-15)
    Article
    Open Access
    We report on the generation of a 2500 nm bandwidth frequency comb at 6.5 μm central wavelength based on critically phase-matched parametric down-conversion in the nonlinear crystal CdSiP 2 CdSiP2 (CSP), driven by a ...
  • High-power sub-two-cycle mid-infrared pulses at 100 MHz repetition rate 

    Pupeza, I.; Sánchez, D.; Zhang, J.; Lilienfein, N.; Seidel, M.; Karpowicz, N.; Paasch-Colberg, T.; Znakovskaya, I.; Pescher, M.; Schweinberger, W.; Pervak, V.; Fill, E.; Pronin, O.; Wei, Z.; Krausz, F.; Apolonski, A.; Biegert, Jens (Nature Publishing Group, 2015-09-21)
    Article

    Powerful coherent light with a spectrum spanning the mid-infrared (MIR) spectral range is crucial for a number of applications in natural as well as life sciences, but so far has only been available from large-scale ...
  • Mining gradual dependencies with variation strength 

    Molina, C.; Serrano, J.M.; Sánchez, D.; Vila, M.A. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
    Article
    Open Access
    In this paper we propose a definition of gradual dependence as a fuzzy association rule. Gradual dependencies represent tendencies in the variation of the degree of fulfilment of properties in a set of objects. We define ...
