  5. 24. Compression and Shaping of Femtosecond Laser Pulses for Coherent Two-Dimensional Nanoscopy

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

    Author : Lukas Wittenbecher; [2016]
    Keywords : Femtosecond pulse shaping; Ultrafast optics; Liquid crystal spatial light modulator; Coherent two-dimensional nanoscopy; Dispersion compensation; Physics and Astronomy;

    Abstract : Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-defined laser pulse sequences. READ MORE

  6. 25. 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
