    • Simulation System For Optical Science (SISYFOS) - tutorial 

      Arisholm, Gunnar; Fonnum, Helge (2012-10-31)
      Sisyfos is a program for simulation of optical parametric frequency conversion, lasers, and beam propagation in nonlinear or turbulent media. The main part of Sisyfos is a C++ library with classes corresponding to optical ...

    • Thermal effects in end-pumped solid state lasers - influence on resonator stability, beam quality, and output power 

      Stenersen, Knut; Lippert, Espen; Rustad, Gunnar; Arisholm, Gunnar (2001)
      A theoretical analysis is given of the magnitudes of thermal effects in end-pumped high-power solid state lasers, and their influence on the laser output characteristics, particularly the beam quality and conversion ...

    • Third-generation femtosecond technology 

      FATTAHI, Hanieh; BARROS, HELENA G.; GORJAN, MARTIN; NUBBEMEYER, THOMAS; ALSAIF, BIDOOR; TEISSET, CATHERINE Y.; SCHULTZE, MARCEL; PRINZ, STEPHAN; HAEFNER, MATTHIAS; UEFFING, MORITZ; ALISMAIL, AYMAN; VÁMOS, LÉNÁRD; SCHWARZ, ALEXANDER; PRONIN, OLEG; BRONS, JONATHAN; GENG, XIAO TAO; Arisholm, Gunnar; CIAPPINA, MARCELO; YAKOVLEV, VLADISLAV S.; KIM, DONG-EON; AZZEER, ABDALLAH M.; KARPOWICZ, NICHOLAS; SUTTER, DIRK; Major, Zsuzsanna; Metzger, Thomas; Krausz, Ferenc (2014)
      Femtosecond pulse generation was pioneered four decades ago using mode-locked dye lasers, which dominated the field for the following 20 years. Dye lasers were then replaced with titanium-doped sapphire (Ti:Sa) lasers, ...

    • Ultrafast Pulse Compression in Bulk with > 20 Times Spectral Broadening Factor from a Single Stage 

      Seidel, Marcus; Balla, Prannay; Arisholm, Gunnar; Winkelmann, Lutz; Hartl, Ingmar; Heyl, Christoph M. (2021-11-01)
      We introduce the combination of multi-pass cell and multi-plate spectral broadening. We demonstrate the compression of 110-μJ pulses from 900-fs to 60-fs in a single stage and report broadening to 38-fs transform-limit by ...

    • ZnGep2-based optical parametric oscillator for µm generation 

      Arisholm, Gunnar; Lippert, Espen; Stenersen, Knut; Rustad, Gunnar; Nicolas, Stephane (2004)
      Operation of a ZnGeP2-based optical parametric oscillator (OPO) for generation of 8-11 μm radiation is studied. The primary source used to pump the OPO is a KTP-based OPO pumped by a Nd:YAG laser, giving up to 2 mJ pump ...
