Principles of Lasers by Svelto, Orazio. In preparing the second edition the hope has been that both these aims will be better served as a result of the various improvements made. Most of the basic mathematical framework needed to understand this evolving field is presented. The case of transient laser behavior will be considered in the next chapter. Please give between 2-5 week for delivery.
Recent advances in ultrafast laser technology have led to the generation of light pulses comprising few optical cycles employing different compression techniques. High-order harmonics of ultrashort laser pulses appear in the time domain as a sequence of attosecond bursts of coherent extreme ultraviolet radiation separated by half the optical cycle of the laser field. The use of such nanosource for pump-probe near-field spectroscopy promises to improve both time and space resolution with respect to the current state-of-the-art setups. Prompt shipping and great customer service. A nonadiabatic three-dimensional numerical model was developed, which provides harmonic spectra in remarkable agreement with the experiments.
In previous chapters, we have discussed several features of the components that make up a laser. Using optical parametric amplifiers with different configurations sub-15-fs laser pulses have been generated tunable in the visible and in the near-infrared Pulse-train multiplication based on the temporal Talbot effect in a linearly chirped fiber Bragg grating has been experimentally demonstrated. Every chapter contains a good set of problems, answers to some of which are given in the back. For instance, amplitude transformation and frequency conversion often result in spatial and time transformations occurring as well. A major fraction of a new chapter Chapter 3 is dedicated to the interaction of radiation with semiconductor media, either in a bulk form or in a quantum-confined structure quantum-well, quantum-wire and quantum dot. Assume also that the laser is under optimum pumping conditions.
Professor Svelto is the author of more than 150 scientific papers and his researches have been the subject of more than 50 invited papers and international conferences. This edition corrects several errors introduced in the previous edition. For the 30 fs regime experimental results are compared with spectra calculated by means of a 1D propagation code which partially accounts for 3D focusing effects. In particular we will concentrate on two experimental methods for the generation of high-peak-power, fewoptical-cycle laser pulses with controlled electric field, which are crucial for the generation of isolated attosecond pulses. A promising and simple method is based on the linear propagation of the pulse train in a highly dispersive medium exploiting, in the time domain by multiple pulse interference, a condition analogous to that found in the fractional Talbot effect of diffractive optics. Before beginning a detailed discussion on optical resonators, which is to be the subject of the next Chapter, we introduce in this Chapter a few topics from geometrical and wave optics.
So far, isolated attosecond pulses have been generated by using few-cycle pulses produced by such compression technique, in combination with active stabilization of the carrier-envelope phase. For each laser, after some introductory comments, the following items are generally covered: 1 Relevant energy levels; 2 excitation mechanisms; 3 characteristics of the laser transition s ; 4 engineering details of the laser structure s ; 5 characteristics of the output beam; 6 applications. The chapter closes with a section on laser stabilization. The general introduction is followed by sections on numerous types of lasers, the emphasis being on today's most important sources of coherent light, in particular on solid-state lasers and several types of gas lasers. Gas, Chemical, Free-Electron, and X-Ray Lasers. The somewhat more complicated case of interaction of radiation with molecules or semiconductors will be considered in the next chapter.
In particular, two techniques have been developed, which allow addressing the issues of high peak power or frequency tunability in a wide spectral range, namely: the hollow-fiber compression technique and the optical parametric amplification. In this paper we present recent results obtained on the generation of ultra-high repetition rate optical pulse trains at in asynchronously frequency-modulated Er—Yb : glass lasers. For example, the amplitude of a cw laser beam may be temporally modulated by an electro-optic or acousto-optic modulator or the time duration of a laser pulse may be increased pulse expansion or decreased pulse compression using suitably dispersive optical systems or nonlinear optical elements. These new developmentsinclude, among others, Quantum-Well and Multiple-Quantum Well lasers, diode-pumpedsolid-state lasers, new concepts for both stable and unstable resonators, femtosecond lasers, ultra-high-brightness lasers etc. Pages and cover are clean and intact. The book can be recommended without constraint especially to advanced undergraduate students who look for a broad overview of modern laser physics and technology. The apparatus consists of a dye laser pumped by a nitrogen laser, a microscope system, and a digital signal averager.
Before it is put to use, a laser beam is generally transformed in some way. Used - Very Good, Versandfertig in 1 - 2 Werktagen, 5. Used - Very Good, Expédition sous 3 à 4 jours ouvrés, En stock. All pages and covers are readable. For a more refined treatment one should use either the semiclassical approach in which the matter is quantized while the e. Usually ships within 24 hours.
In particular high-order harmonic generation in the few-optical-cycle regime is attractive for the generation of soft-x-ray pulses with duration down to the sub-femtosecond range. A second type of transformation, also rather frequently encountered, is that which occurs when the beam is passed through an amplifier or chain of amplifiers. We discuss two techniques for generating such pulses: broad-band parametric amplification, which allows the generation of pulses in the visible range suitable for spectroscopy, and compression of high-energy light pulses in a hollow fiber. We demonstrate that transmission through hollow pyramid probes with diameter down to 65 nm has negligible effects on the duration of pulses as short as 30 fs. Its mission remains to provide a broad, unified description of laser behavior, physics, technology, and applications.
The new rod-imaging unstable resonator configuration that we have recently introduced is theoretically analysed and experimentally characterized. For many years, this book has been the standard against which other textbooks in this field were measured, mostly unfavourably. The book can be recommended without constraint especially to advanced undergraduate students who look for a broad overview of modern laser physics and technology. The active waveguide is fabricated in an Er—Yb-doped phosphate glass, and the mode locker is a fiber-pigtailed saturable absorber device based on single-wall carbon nanotubes specially designed to efficiently operate at 1. Most of the basic mathematical framework needed to understand this evolving field is presented. They will first be considered within the simplifying assumptions of a dilute medium and a low intensity. The book is thereforeintendedas a text-bookfor a senior-levelor? The recent availability of high-peak-power few-optical-cycle light pulses has opened the way to the investigation of light-matter interaction in the strong-field regime with unprecedented temporal resolution.
The spectral properties of harmonic radiation generated in neon by laser pulses with duration from 30 fs down to 5 fs have been investigated. In this chapter, the most important types of lasers involving high density active media are considered, namely solid-state, dye and semiconductor lasers. Usually ships within 24 hours.

As an example of application in time-resolved spectroscopy we report results of pump—probe experiments in a prototypical conjugated molecule, namely sexithiophene. The main emphasis, again, is to stress the physical behavior of the laser and to relate this behavior to the general concepts developed in the previous chapters.
