When I was first approached to edit a volume on Femtosecond Laser
Spectroscopy in 2000, I did not anticipate that the field was about to explode,
with the announcement of a series of remarkable new developments and
advances. This volume describes these recent developments in eleven
chapters written by leading international researchers in the field. It includes
Femtosecond optical frequency combs, which are currently
revolutionising ultrahigh precision spectroscopy and optical frequency
Ebook Femtosecond laser pulses principles and experiments is compiled with the content: Laser Basics, Pulsed Optics, Methods for the Generation of Ultrashort Laser Pulses Mode-Locking, Further Methods for the Generation of Ultrashort Optical Pulses, Pulsed Semiconductor Lasers, How to Manipulate and Change the Characteristics of Laser Pulses,... Invite you to consult the document details.
This book discusses aspects of laser pulses generation, characterization, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. The introductive chapter shortly overviews the physical principles of pulsed lasers operation with pulse durations from seconds to yoctoseconds. A theory of mode-locking, based on the optical noise concept, is discussed. With this approximation, all paradoxes of ultrashort laser pulse formation have been explained.

Over the last few years, there has been a convergence between the fields
of ultrafast science, nonlinear optics, optical frequency metrology, and
precision laser spectroscopy. These fields have been developing largely
independently since the birth of the laser, reaching remarkable levels of

the generation of ultrashort laser pulses. Beginning with mode-locking of
glass lasers in the 1960s, the development of dye lasers brought the pulse
width down from picoseconds to femtoseconds. The breakthrough in solid
state laser pulse generation provided the current reliable table-top laser
systems capable of average power of about 1 watt, and peak power density
of easily watts per square centimeter, with pulse widths in the
range of four to eight femtoseconds.
This book deals with theoretical and experimental aspects of solid-state lasers, including optimum waveguide design of end pumped and diode pumped lasers. Nonlinearity, including the nonlinear conversion, up frequency conversion and chirped pulse oscillators are discussed. Some new rare-earth-doped lasers, including double borate and halide crystals, and feedback in quantum dot semiconductor nanostructures are included.
Recent advents in laser technology and discoveries in laser physics have enabled their
very new and exciting applications. Some of them cover production of new materials:
nano-particles, periodic structures in nano-scale, and thin films. Others allowed better
understanding of laser-matter interaction when sample is subjected to intense laser
pulses of various time duration, shape in space and time domains as well as different
spectral components contained in a pulse.

Synthesis of magnetic nanofibers using femtosecond laser material processing in air
Mohammed-Amin Alubaidy1, Krishnan Venkatakrishnan1* and Bo Tan2
Abstract In this study, we report formation of weblike fibrous nanostructure and nanoparticles of magnetic neodymiumiron-boron (NdFeB) via femtosecond laser radiation at MHz pulse repetition frequency in air at atmospheric pressure.
The studies of ultrashort laser pulse interactions with single atoms, molecules,
nanoparticles and condensed matter is a hot topic of modern physics, since the
obtained results stimulate the development of fundamental principles of light-matter
interaction and, at the same time, find the wide area of practical applications.
This volume contains the contributions devoted both to the discussion of general
principles and fundamental experiments, as well as the different practical applications.
Lithography, the fundamental fabrication process of semiconductor devices, plays a critical role in micro- and nano-fabrications and the revolution in high density integrated circuits. This book is the result of inspirations and contributions from many researchers worldwide. Although the inclusion of the book chapters may not be a complete representation of all lithographic arts, it does represent a good collection of contributions in this field. We hope readers will enjoy reading the book as much as we have enjoyed bringing it together.
Optical fibers, an important and promising material, have been the subject of intensive
research and development due to their many scientific and practical applications. They
are designed to guide light along its length by confining as much light as possible in
its core. The interaction between the propagating light with the fiber material is the
foundation of the development of various applications such as optical amplifiers, fiber
lasers, sensors etc.
