1. 1. Evaluation of the wavefronts and spatial structures of ultrashort pulses passing through a micro-channel plate

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Simon Ek; [2019]
   Nyckelord :high-order harmonic generation; HHG; micro-channel plate; MCP; attophysics; Physics and Astronomy;

   Sammanfattning : The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. LÄS MER

3. 2. Interferometer Design for Attosecond Experiments

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen

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

   Sammanfattning : 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). LÄS MER
