  1. 16. Design of Multilayer Dielectric Mirrors Optimized for Femtosecond Laser Pulses

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

    Author : Fredrik Bertilsson; [2015]
    Keywords : Physics and Astronomy;

    Abstract : A general method for modelling reflection in a multilayer structure is developed. This is used to simulate how a Gaussian Ti:sapphire femtosecond pulse reflects off of a periodic SiO2/TiO2 dielectric stack at normal incidence. The method is based on a transfer matrix approach combined with the fast Fourier transform in MATLAB. READ MORE

  3. 17. Interferometer Design for Attosecond Experiments

    University essay from Lunds universitet/Fysiska institutionen

    Author : Simon Ek; [2015]
    Keywords : FRED; attophysics; atomic physics; stability; simulations; MATLAB; interferometer design; interferometers; error propagation; Physics and Astronomy;

    Abstract : Resolving fast events, such as electron dynamics, requires short light pulses. To this date the shortest available light pulses are created using High-order Harmonic Generation (HHG) and have a duration of a few hundred attoseconds (1 as = $10^{-18}$ s). READ MORE

  4. 18. Breathing adapted radiotherapy using optical real-time thoractic localization

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rebecca Ljungqvist; [2014]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: The aim of this work is to investigate the ability of a laser positioning system for breathing-adapted radiotherapy (BART), also known as respiratory gating. C-RAD installed the Sentinel system at the Sk°ane University Hospital (SUS) in Malm¨o during an appointed time for the purpose of evaluation on the pre-clinical gating prototype. READ MORE

  5. 19. Circular Modulation Formats and Carrier Phase Estimation for Coherent Optical Systems

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sebastian Joel Ortega Zafra; [2014]
    Keywords : ;

    Abstract : Digital coherent receivers stand today as a promising technology for the next generation of high-capacity optical systems. Coherent systems enable the use of multilevel modulation formats which increase the spectral efficiency of a system. READ MORE

  6. 20. Stabilization of an optical frequency comb to an external cavity

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olof Rydberg; [2014]
    Keywords : ;

    Abstract : The subject of this master's thesis is stabilizing a frequency comb laser to an external cavity using a couple of servo controllers. The aim of the project was to build a pair of servo controllers, replacing parts of the existing commercial and proprietary solution already in use. READ MORE
