English | ISBN: 1607410095 | 2009 | 483 pages | PDF | 20 MB
There has been a remarkable upsurge in the importance of high power lasers in the past decade. This book presents an overall survey of recent advances in high peak power solid lasers and reviews recent results in the interaction of high power laser pulses with various dielectric materials containing metal nanoparticles. This book also presents the basics as well as the theory of a single crystal photo-elastic modulator and a consideration of modern approaches to the synthesis of diffractive optical elements for technological IR-laser beams focusing. During ultrafast laser interaction with metal, the electrons and lattices are not in equilibrium. This book presents various two-temperature models that can be used to describe the non-equilibrium heat transfer as well as the results of techniques in high power femtosecond laser machining of metals. This book presents an overview of the current state of the art in the field of femtosecond technology with a special emphasis on the research of high-intensity laser-matter interactions. An investigation of non-linear excitation imaging technique including two-photon autofluorescence and second harmonic generated signal imaging is presented to investigate the microstructures of whole-mount corneal, retinal, and scleral tissues in their native environment. Finally, included is a review of recent semi-classical excited-state dynamics simulation results of some complex molecular systems and a report of the dynamics of confined excitons when several exciton states are excited.

Free Download Introduction to Ultrafast Phenomena: From Femtosecond Magnetism to High-Harmonic Generation by Guo-ping Zhang, Georgios Lefkidis, Mitsuko Murakami
English | December 9, 2020 | ISBN: 1498764282 | 300 pages | MOBI | 24 Mb
This book, the first of this kind, provides a comprehensive introduction to ultrafast phenomena, covering the fundamentals of ultrafast spin and charge dynamics, femtosecond magnetism, all-optical spin switching, and high-harmonic generation. It covers the experimental tools, including ultrafast pump-probe experiments, and theoretical methods including quantum chemistry and density functional theory, both time-independent and time-dependent. The authors explain in clear language how an ultrafast laser pulse is generated experimentally, how it can induce rapid responses in electrons and spins in molecules, nanostructures and solids (magnetic materials and superconductors), and how it can create high-harmonic generation from atoms and solids on the attosecond timescale. They also show how this field is driving the next generation of magnetic storage devices through femtomagnetism, all-optical spin switching in ferrimagnets and beyond, magnetic logic in magnetic molecules, and ultrafast intense light sources, incorporating numerous computer programs, examples, and problems throughout, to show how the beautiful research can be done behind the scene.
