Book Synopsis Femtosecond Laser Spectroscopy by : Peter Hannaford
Download or read book Femtosecond Laser Spectroscopy written by Peter Hannaford and published by Springer Science & Business Media. This book was released on 2005-12-27 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The embryonic development of femtoscience stems from advances made in 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. Pulses with peak power density reaching watts per square centimeter have been achieved in laboratory settings and, more recently, pulses of sub-femtosecond duration have been successfully generated. As concepts and methodologies have evolved over the past two decades, the realm of ultrafast science has become vast and exciting and has impacted many areas of chemistry, biology and physics, and other fields such as materials science, electrical engineering, and optical communication. In molecular science the explosive growth of this research is for fundamental reasons. In femtochemistry and femtobiology chemical bonds form and break on the femtosecond time scale, and on this scale of time we can freeze the transition states at configurations never before seen. Even for n- reactive physical changes one is observing the most elementary of molecular processes. On a time scale shorter than the vibrational and rotational periods the ensemble behaves coherently as a single-molecule trajectory.

Book Synopsis Femtosecond Optical Frequency Comb: Principle, Operation and Applications by : Jun Ye
Download or read book Femtosecond Optical Frequency Comb: Principle, Operation and Applications written by Jun Ye and published by Springer Science & Business Media. This book was released on 2006-06-15 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.

Book Synopsis Numerical Studies of Femtosecond Laser Spectroscopy Experiments in Gallium Arsenide Material and Quantum Well Structures by : Daniel William Bailey
Download or read book Numerical Studies of Femtosecond Laser Spectroscopy Experiments in Gallium Arsenide Material and Quantum Well Structures written by Daniel William Bailey and published by . This book was released on 1990 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis the methods and results of numerical simulations of femtosecond laser spectroscopy experiments in Al$sb{x}$Ga$sb{1-x}$As quantum well structures and bulk GaAs are presented. Photoexcited carriers are modeled by an ensemble Monte Carlo method including hole bandstructure effects. The time-dependent distributions from the Monte Carlo simulations in turn serve as a basis for interpreting transient differential transmission data, leading to an understanding of relaxation processes and the determination of material parameters in Al$sb{x}$Ga$sb{1-x}$As quantum wells and GaAs. In Chap. 2 the Al$sb{x}$Ga$sb{1-x}$As quantum well system is examined by electron ensemble Monte Carlo simulations of 2-eV and near-band edge laser spectroscopy experiments. Results are contrasted, where appropriate, with comparable simulations in bulk GaAs. Simulations show that, unlike bulk experiments, the effects of polar optical phonon scattering are obscured in Al$sb{x}$Ga$sb{1-x}$As quantum well measurements because of coupling between hole subbands. Three scattering mechanisms are investigated and discussed: electron-electron, polar optical phonon, and (intervalley) optical deformation potential. Femtosecond laser spectroscopy experiments in bulk GaAs are studied in Chap. 3. Electron and hole dynamics are modeled simultaneously. The time-dependent distribution functions from the ensemble Monte Carlo simulation are used to obtain the differential transmission directly, thus avoiding problems imposed by extracting time constants from the experimental spectra. By matching experimental results and artificially varying the strength of scattering mechanisms, dominant and sensitive relaxation mechanisms are clearly identified. These simulations show that for 2-eV femtosecond laser spectroscopy measurements in GaAs at room temperature, for electrons the intervalley scattering rate is the most critical parameter determining the width of the initial transient transmission peak, and that the best fit with experimental results occurs for $Dsb{o}$ = 5 $times$ 10$sp8$ eV/cm. Equally important in the analysis, however, is the effect of holes on the differential transmission. It is also shown that carrier-carrier scattering plays a much less important role.
