Theory of Nonlinear Propagation of excessive Harmonics Generated in a Gaseous Medium establishes the theoretical instruments to review High-Order Harmonic new release (HHG) via excessive ultrafast infrared lasers in atoms and molecules. The macroscopic propagation of either laser and high-harmonic fields is considered through fixing Maxwell's wave equations, whereas the single-atom or single-molecule reaction is handled with a quantitative rescattering thought by way of fixing the time-dependent Schrödinger equation.
This publication demonstrates for the 1st time that saw experimental HHG spectra of atoms and molecules will be thoroughly reproduced theoretically while certain experimental stipulations are recognized. The macroscopic HHG should be expressed as a manufactured from a macroscopic wave packet and a photorecombination move part, the place the previous is determined by laser and experimental stipulations whereas the latter is the valuables of aim atoms or molecules. The factorization makes it attainable to retrieve microscopically atomic or molecular constitution details from the measured macroscopic HHG spectra.
This e-book additionally investigates different very important concerns approximately HHG, akin to contributions from a number of molecular orbitals, the minimal within the HHG spectrum, the spatial mode of laser beams, and the new release of an remoted attosecond pulse. also, this publication offers the photoelectron angular distribution of aligned molecules ionized via the HHG light.
