WebJun 24, 2024 · Abstract: A possibility of producing laser pulse shaping of infrared chirped pulses (1nm spectral width, 1 ns duration) is investigated. It is shown, that SLM-based shaper can be used for the pulse shape precompensation before an amplifier chain Published in: 2024 International Conference Laser Optics (ICLO) Article #: WebSeveral authors have utilized optical force, through the linearly chirped laser pulses, for slowing down, acceleration [13] and forced rotation [14] of molecules. It is worthwhile to mention that in late seventies, in an experimental study, Bjorkholm et al. [15] demonstrated the phenomena of focusing, defocusing and steering of neutral sodium ...
WebOct 12, 2008 · Oppositely chirped laser pulses are combined at a beam-splitter. The output beams are recombined and focused onto a nonlinear crystal after one of the beams has passed through a sample. WebA petawatt is a quadrillion watts, or roughly 1/200th of the total power of sunlight striking the Earth’s atmosphere. The technique relies on grooved surfaces called diffraction gratings to stretch a very short duration laser pulse so that it lasts 50,000 times longer.
