1. 1. Generation of Ultrashort Pulses – From Femtoseconds to Attoseconds

   Författare :Maite Louisy; Atomfysik; []
   Nyckelord :Attosecond; Femtosecond; Ultrashort laser pulses; Ultrafast optics; High-order harmonic generation; extreme ultraviolet; Post-compression; Hollow-core capillary; d-scan; Optical gating; Fysicumarkivet A:2017:Louisy;

   Sammanfattning : Electronic dynamics takes place on the attosecond timescale and can thus only be studied using a tool with attosecond temporal resolution. High harmonic generation (HHG) provides coherent attosecond pulses in the extreme ultraviolet spectral region. LÄS MER

3. 2. Generation, characterization and application of infrared few-cycle light pulses

   Författare :Ivan Sytcevich; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Few-cycle pulses; pulse characterization; optical parametric amplification; Fysicumarkivet A:2022:Sytcevich;

   Sammanfattning : In recent decades, laser systems emitting pulses of light containing only a few electric field oscillations under their envelope have become common in many ultrafast optics laboratories. Owing to unique temporal characteristics and achieving extreme field strengths, these so-­called few­-cycle pulses have been instrumental in unlocking new regimes of light-­matter interaction. LÄS MER
