    We present efficient high-order harmonic generation (HHG) based on a high-repetition rate, few-cycle, near infrared (NIR), carrier-envelope phase stable, optical parametric chirped pulse amplifier (OPCPA), emitting 6 fs ...
  • Hinkelmann, Moritz; Wandt, Dieter; Morgner, Uwe; Neumann, Jörg; Kracht, Dietmar (Washington, DC : Optical Society of America, 2018)
    We report on CPA-free multipass amplification of ps-pulses in Holmium-doped yttrium lithium fluoride (Ho:YLF) crystals up to µJ pulse-energy-covering repetition rates from 10 kHz up to 500 kHz. The seed pulses at a wavelength ...
  • Kurz, Heiko G.; Steingrube, Daniel S.; Ristau, Detlev; Lein, Manfred; Morgner, Uwe; Kovacev, Milutin (College Park, MD : American Physical Society, 2013)
    We report on high-order-harmonic generation from micrometer-sized liquid water droplets. In pump-probe experiments, the influence of the time delay onto the emission of harmonic radiation is systematically studied. ...
  • Müller, M.; Hammerer, Klemens; Zhou, Y.L.; Roos, C.F.; Zoller, P. (Bristol : IOP Publishing Ltd., 2011)
    In a recent experiment, Barreiro et al (2011 Nature 470 486) demonstrated the fundamental building blocks of an open-system quantum simulator with trapped ions. Using up to five ions, dynamics were realized by sequences ...
  • Brée, C.; Hofmann, M.; Demircan, A.; Morgner, Uwe; Kosareva, O.; Savel'Ev, A.; Husakou, A.; Ivanov, M.; Babushkin, I. (American Physical Society, 2017)
    The ionization rate of an atom in a strong optical field can be resonantly enhanced by the presence of long-living atomic levels (so-called Freeman resonances). This process is most prominent in the multiphoton ionization ...
  • Berski, Fabian; Kuhn, Hendrik; Lonnemann, Jan G.; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2013)
    We advance all optical spin noise spectroscopy (SNS) in semiconductors to detection bandwidths of several hundred gigahertz by employing a sophisticated scheme of pulse trains from ultrafast laser oscillators as an optical ...
  • Hinkelmann, Moritz; Wandt, Dieter; Morgner, Uwe; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : S P I E - International Society for Optical Engineering, 2018)
    We present CPA-free linear amplification of 6:3 ps pulses in Ho:YLF crystals up to 100 μJ pulse energy at 10 kHz repetition rate. The seed pulses at a wavelength of 2:05 μm are provided by a Ho-based all-fiber system ...
