Femtosecond pulses

Xem 1-11 trên 11 kết quả Femtosecond pulses
  • 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.

  • 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 performance.

  • 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.
