  1. 1. Evaluation of white-light generation as possible seed for a mid-infrared optical parametric chirped pulse amplifier

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Chuang Lu; [2017]
    Keywords : nonlinear linear optics; ultrafast optics; Mid-infrared generation; near-infrared; Optical parametric amplification; Optical Parametric Chirped-pulse Amplification; supercontinuum generation; white-light generation; laser induced filamentation; Dispersion-scan; nonlinear propagation; Physics and Astronomy;

    Abstract : White-light spectra of different crystals, based on 1030-nm intense pump pulses have been investigated in order to derive a near-infrared seed for mid-infrared generation. Among ten crystals, YAG (yttrium aluminium garnet), KGW (potassium gadolinium tungstate) and YVO4 (yttrium orthovanadate) exhibit the most suitable properties for supercontinuum generation with high efficiency for spectral broadening as well as high tolerance to optical damage.

  3. 2. Commissioning and Characterization of Two Undulators at the MAX IV 3 GeV Storage Ring

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sara Mikaelsson; [2016]
    Keywords : accelerator physics; MAX IV; insertion device pertubations; beam dynamics; orbit correction; Physics and Astronomy;

    Abstract : Insertion devices have several undesirable effects on the beam dynamics of a synchrotron storage ring, and these must be compensated for in order to ensure long term stable operation. This master’s thesis concerns the two first insertion devices at the MAX IV facility, two in-vacuum undulators for the BioMAX and NanoMAX beamlines. READ MORE

  4. 3. Separation of lobes in Multispectral Digital Holography

    University essay from Institutionen för fysik

    Author : Örn Hjartarson; [2013]
    Keywords : Holography Holographic Optics Lobes Electromagnetism Non-invasive;

    Abstract : Through a holographic recording a property from the third dimension, the depth, is obtained in the form of a phase map of the incident light. One wavelength holography will have a unique phase for the depth range corresponding to the wavelength of the light and outside this range the real depth can not be resolved. READ MORE
