15. Generation, characterization and application of infrared few-cycle light pulses
Abstract : 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. READ MORE
