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.
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.
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
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.
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.

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.
