  • Melchert, O.; Morgner, Uwe; Roth, B.; Babushkin, I.; Demircan, A. (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    We present a numerical approach for the accurate simulation of the complex propagation dynamics of ultrashort optical pulses in nonlinear waveguides, especially valid for few-cycle pulses. The propagation models are derived ...
  • Ishii, Atsuhiro; Ariyasu, Kazumasa; Mitsuhashi, Tatsuki; Heinemann, Dag; Heisterkamp, Alexander; Terakawa, Mitsuhiro (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The use of small particles has expanded the capability of ultrashort pulsed laser optoinjection technology toward simultaneous treatment of multiple cells. The microfluidic platform is one of the attractive systems that ...
  • Gruene, Martin; Unger, Claudia; Koch, Lothar; Deiwick, Andrea; Chichkov, Boris (London : Biomed Central, 2011)
    Background: Laser-assisted bioprinting of multi-cellular replicates in accordance with CAD blueprint may substantially improve our understandings of fundamental aspects of 3 D cell-cell and cell-matrix interactions in ...
  • Tinne, Nadine; Knoop, Gesche; Kallweit, Nicole; Veith, Sonja; Bleeker, Sebastian; Lubatschowski, Holger; Krüger, Alexander; Ripken, Tammo (Bellingham, WA : SPIE - International Society for Optical Engineering, 2014)
    We present a time-resolved photographic analysis of the pulse-to-pulse interaction. In particular, we studied the influence of the cavitation bubble induced by a fs-pulse on the optical focusing of the consecutive pulse ...
  • Tudorovskaya, Maria; Lein, Manfred (College Park, MD : American Physical Society, 2017)
    The spectrum of a high-repetition train of laser pulses consists of many equally spaced lines, forming an optical frequency comb which is useful for high-precision spectroscopy. By exposing atoms to a train of strong pulses, ...
  • Kracht, D.; Sayinc, H.; Yilmaz, S.; Wysmolek, M.; Hausmann, K.; Ottenhues, C.; Wandt, D.; Wienke, A.; Neumann, J. (Amsterdam : Elsevier B.V., 2016)
    We report on a variety of continuous wave and pulsed laser sources based on Thulium- and Holmium-doped materials, emitting in the spectral range around 2 μm. This includes continuous wave Thulium-doped fiber lasers which ...
  • Schmitt-Sody, Andreas; Kurz, Heiko G.; Bergé, Luc; Skupin, Stefan; Polynkin, Pavel (Bristol : Institute of Physics Publishing, 2016)
    The propagation of intense picosecond laser pulses in air in the presence of strong nonlinear self-action effects and air ionization is investigated experimentally and numerically. The model used for numerical analysis is ...
  • Henkel, Jost; Witting, Tobias; Fabris, Davide; Lein, Manfred; Knight, Peter L.; Tisch, John W.G.; Marangos, Jonathan P. (College Park, MD : American Physical Society, 2013)
    Attosecond light pulses within the vacuum ultraviolet (VUV) energy range are predicted by solving the time-dependent Schrödinger equation (TDSE) for a model neon atom in short laser pulses of different field polarization ...
  • Liu, Yunquan; Tschuch, S.; Rudenko, A.; Dürr, M.; Siegel, M.; Morgner, Uwe; Moshammer, R.; Ullrich, J. (American Physical Society, 2008)
    Nonsequential double ionization of Ar by 45 fs laser pulses (800 nm) at (4-7)×1013W/cm2 was explored in fully differential measurements. Well below the field-modified recollision threshold we enter the multiphoton regime. ...
  • Hinderthür, H.; Ruschewitz, F.; Lohe, H.-J.; Lechte, S.; Sengstock, K.; Ertmer, Wolfgang (American Physical Society, 1999)
    We report on experiments of multiple-beam atom interferometry in the time domain. Laser-cooled and trapped atoms interact with atomic "multiple beam splitters" realized by time sequences of resonant laser pulses. The output ...
  • Lubatschowski, Holger (Amsterdam : Elsevier B.V., 2010)
    Ultrafast laser pulses have become a promising tool for microsurgery of the eye. Due to the low energy threshold, side effects are limited to the micrometer range This precision enables the use of ultrashort laser pulses ...
