Book Description
Continuous laser action has been observed on several HF and DF vibrational-rotational transitions. The HF lases between 2.6 and 2.9 microns, and the DF lases between 3.6 and 4.1 microns. The lines are identified and the relative intensities are shown. (Author).

Book Description
The report summarizes a research program on chemical lasers. Parametric studies of the HF, DF, HF-CO2, and DF-CO2 purely chemical lasers were accomplished with a prototype system to provide design data for CO2 lasers of multikilowatt size. The second phase of the grant resulted in accurate determinations of vibrational matrix elements and the dipole moment function for HF and DF molecules. Vibrational matrix elements were measured through the fifth overtone for both molecules. Additional investigations were launched at the end of the grant period directed toward the discovery of new chemical laser systems capable of operation at visible wavelengths.

Book Description
Molecular Spectroscopy: Modern Research explores the advances in several phases of research in molecular spectroscopy. This eight-chapter book commemorates the 25th anniversary of the annual Columbus Symposium on Molecular Structure and Spectroscopy, held in September, 1970. This book highlights the spectroscopic studies of molecular species in the gas phase and in matrices. Representative articles are also included that cover the applications of molecular studies in a wide variety of areas such as biophysics, astrophysical problems, and energy transfer processes. Other chapters describe the progress achieved in the technology of high resolution spectroscopy and the techniques and terminology of Lamb-dip spectroscopy. A comprehensive bibliography is included for most of the subjects discussed and this text concludes with tables of standard data listing secondary wavelength standards, fundamental constants, atomic masses, and conversion factors of interest to spectroscopists. Spectroscopists, chemists, and researchers will find this work invaluable.

Book Description
This book explores new principles of Self-Initiating Volume Discharge for creating high-energy non-chain HF(DF) lasers, as well as the creation of highly efficient lasers with output energy and radiation power in the spectral region of 2.6–5 μm. Today, sources of high-power lasing in this spectral region are in demand in various fields of science and technology including remote sensing of the atmosphere, medicine, biological imaging, precision machining and other special applications. These applications require efficient laser sources with high pulse energy, pulsed and average power, which makes the development of physical fundamentals of high-power laser creation and laser complexes of crucial importance. High-Energy Ecologically Safe HF/DF Lasers: Physics of Self-Initiated Volume Discharge-Based HF/DF Lasers examines the conditions of formation of SSVD, gas composition and the mode of energy input into the gas on the efficiency and radiation energy of non-chain HF(DF) lasers. Key Features: Shares research results on SSVD in mixtures of non-chain HF(DF) lasers Studies the stability and dynamics of the development of SSVD Discusses the effect of the gas composition and geometry of the discharge gap (DG) on its characteristics Proposes recommendations for gas composition and for the method of obtaining SSVD in non-chain HF(DF) lasers Develops simple and reliable wide-aperture non-chain HF(DF) lasers and investigates their characteristics Investigates the possibilities of expanding the lasing spectrum of non-chain HF(DF) lasers

Book Description
This volume represents the most complete, up-to-date compilation of wavelengths of lasers in all media. Divided by type - solid, liquid, and gas - and listed in order of increasing wavelength, Handbook of Laser Wavelengths includes: crystalline paramagnetic ion lasers glass lasers color center lasers semiconductor lasers polymer lasers liquid and solid-state dye lasers rare earth liquid lasers neutral atom, ion, and molecular gas lasers extreme ultraviolet and soft X-ray lasers free electron lasers nuclear-pumped lasers lasers in nature lasers without inversion Brief descriptions of each type of laser are presented, followed by tables listing the laser wavelength, lasing element or medium, host, transition, and primary literature citations. A special section on commercial lasers is an added featured. Handbook of Laser Wavelengths singularly serves as the essential reference for scientists and engineers searching for laser sources for specific applications as well as a survey of the developments that have occurred since the advent of the laser.

Book Description
Lasers continue to be an amazingly robust field of activity. Anyone seeking a photon source is now confronted with an enormous number of possible lasers and laser wavelengths to choose from, but no single, comprehensive source to help them make that choice. The Handbook of Lasers provides an authoritative compilation of lasers, their properties, and original references in a readily accessible form. Organized by lasing media-solids, liquids, and gases-each section is subdivided into distinct laser types. Each type carries a brief description, followed by tables listing the lasing element or medium, host, lasing transition and wavelength, operating properties, primary literature citations, and, for broadband lasers, reported tuning ranges. The importance and value of the Handbook of Lasers cannot be overstated. Serving as both an archive and as an indicator of emerging trends, it reflects the state of knowledge and development in the field, provides a rapid means of obtaining reference data, and offers a pathway to the literature. It contains data useful for comparison with predictions and for developing models of processes, and may reveal fundamental inconsistencies or conflicts in the data.

Book Description
This volume contains the lectures presented at the NATO Advanced Study Institute on "Frontiers of Laser Spectroscopy of Gases" held in the Hotel Golf Mar, Vimeiro, near Torres Vedras, Portugal from 30 March to 10 April 1987. The objective of the meeting was to take stock of the recent technological developments involving lasers and to assess their impact on spectroscopy. The whole range of wavelengths from the far infrared through to the extreme ultraviolet was covered. In addition, specific applications to both atoms and molecules were described. Indeed, one of the most successful and pleasant aspects of the Institute was the joint participation of atomic physicists and molecular spectro scopists, who meet all too rarely these days. The Institute also succeeded in covering a wide time span from the very earliest days of lasers to some of the very latest developments in both lasers and their applications to spectroscopy. There were 14 invited lecturers, giving a total of 40 lectures, and 89 other participants at the Institute. Each of the invited lecturers has contributed a chapter to this volume. In addition, on Thursday 2nd April a special one-day session was held in the Chemistry Department at the University of Coimbra to mark the retirement of Professor Dr. F.
