Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: The rapid development of lasers in the past few decades has led to their application in almost every field of science and technology. The idea that it should be possible to convert the energy released in chemical reactions of chemical lasers directly into coherent radiation resulted in the advent in the 1960s. These first chemical lasers, however, consumed much more energy to initiate the reaction than they emitted. The search for more ef ficient chemical lasing led to the utilization of chain reactions. However, care had to be taken to maintain the appropriate pressure. In 1970, it was demonstrated that the operation of chemical lasers at atmospheric pressure was also feasible, making it easier and cheaper to construct them. One of the advantages of chemical lasers is the wide range of radia tion wavelengths emitted by them: 1.3 - 26 ~m. The vibrational frequen cies of many molecules fall within this range so that they may convenient ly be used for the operation of such lasers. Progress in the development of chemical lasers is intimately con nected with advances in related fields such as gas dynamics, chemical reaction kinetics, and research into the energy relaxation and transfer processes in molecular systems.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of HF chemical lasers operating on overtone transitions, OTs, in a photolytically initiated, pulsed laser facility was conducted. The primary objective was to obtain comparisons of the specific energy performance of pulsed HF, chain reaction driven, chemical laser resonators when operating only on fundamental transitions, delta V = 1, and only on first overtone transitions, delta V = 2. The initial efforts were the buildup of the experimental test facility with which excellent performance as an FT HF laser was demonstrated. However, attempts to produce OT lasing using lamda- variable reflectivity mirror coatings (to promote and suppress, simultaneously, the OT and FT mechanisms) were only marginally successful, even though major facility modifications were made to reduce cavity losses, suppress FT superradiance (ASE), suppress parasitic modes and increase pulse duration. Finally, CW OT lasing was demonstrated using the OT optical components in a combustion-driven, blowdown test facility. A specific energy level, sigma = 266 w/gm/sec, was inferred from the measurements. HF Chemical lasers, HF Overtone lasers, Pulsed photolytically initiated chemical lasers.

Download or read book Performance Evaluation and Reaction Kinetics of a Pulsed HF Laser written by J. D. McClure and published by . This book was released on 1973 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variation of performance of a laser-initiated HF laser with variation in reagent concentrations, reagent-diluent concentration ratio, and initial dissociation level is described. The HF laser intensity transients exhibit characteristic temporal structure representative of free-running chain reactions and collisional transfer processes in reacting H2 - F2 mixtures. Explicit exposure of underlying mechanisms is achieved by fast dissociation of F2 via second harmonic radiation derived from a Q-switched ruby laser pulse, and by simultaneous time-resolved spectral measurements of laser emission on a number of vibration-rotation transitions. Continued laser emission over many chain-reaction steps, even for relatively low dissociation levels, supports the position that pulsed chemical lasers are attractive candidates for high power applications.

This book was released on 1970 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser action was observed for the first time in several new chemical systems in which HF was produced following a pulsed electrical discharge. The use of transverse multiple discharges enabled high pulse energies and peak powers to be obtained. It was possible to correlate the energy measurements and the spectroscopic output with the exothermicity of the reaction F + RH = HF + R. (Author).
