Book Synopsis High-Power Laser Radiation in Atmospheric Aerosols by : V.E. Zuev
Download or read book High-Power Laser Radiation in Atmospheric Aerosols written by V.E. Zuev and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unique properties of laser radiation including its monochromatic properties, polarization, high spectral intensity, coherence, narrow beam divergence, the possibility of controlling the pulse duration and radiation spectrum and, finally, the fact that extremely high power and energy create very favorable conditions for the extensive application of lasers to communi cation systems, systems for the lidar sensing and ultra-high-precision ranging, navigation, remote monitoring of the environment, and many other systems operating in the atmosphere. The operative efficiency of the above systems depends significantly on the state of the atmosphere and the corresponding behavior of laser radia tion propagating through it. This circumstance has stimulated the studies of the above regularities during the passt 10-15 years. For the investiga tions to be carried out the scientists were forced to develop new theories and methods for studying the problem experimentally. Moreover, during such investigations some previously unknown phenomena were observed, among them the nonlinear effects accompanying high-power laser radiation propagating through the atmosphere are of paramount importance. Among the nonlinear effects caused by high-power laser radiation inter action with the atmosphere, the effects accompanying the propagation of high-power radiation through the atmospheric aerosols are of particular interest. Aerosols always occur in the atmosphere. It should be noted that the microphysical and optical characteristics of atmospheric aerosols vary widely, this fact causes a great variety in the features of their inter action with radiation.

Book Synopsis Atmospheric Attenuation of Laser Radiation from 0.76 to 31.25 Micrometers by : R. A. McClatchey
Download or read book Atmospheric Attenuation of Laser Radiation from 0.76 to 31.25 Micrometers written by R. A. McClatchey and published by . This book was released on 1974 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution atmospheric transmittance curves are presented for the spectral region 320 to 13,200/cm (0.7576 to 31.25 micrometers). These spectra are useful as a guide for selecting laser wavelengths for atmospheric propagation studies in this spectral region. In addition, this report provides attenuation coefficients for those lines of the CO, HF, DF, and CO2 laser systems which suffer the least atmospheric attenuation. A new aerosol model is introduced here, taking into account recent measurements of the complex index of refraction of aerosol particles. (Author).

This book was released on 2017-09-22 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces optical wave propagation in the irregular turbulent atmosphere and the relations to laser beam and LIDAR applications for both optical communication and imaging. It examines atmosphere fundamentals, structure, and content. It explains specific situations occurring in the irregular atmosphere and for specific natural phenomena that affect optical ray and laser beam propagation. It emphasizes how to use LIDAR to investigate atmospheric phenomena and predict primary parameters of the irregular turbulent atmosphere and suggests what kinds of optical devices to operate in different atmospheric situations to minimize the deleterious effects of natural atmospheric phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: Effects of High-Power Laser Radiation describes the interactions between high-power laser beams and matter. This book is divided into eight chapters that particularly focus on interactions such as heating, melting, vaporization, and plasma production. The opening chapters examine the laser properties, types, measurement techniques, and safety aspects. The succeeding chapters deal with a variety of physical phenomena and mechanisms of laser-induced particle emission, as well as the initiation and development of gas breakdown phenomena. Other chapters explore the effects and damage of various interactions in transparent materials and on biological systems. The final chapter looks into the practical applications of the various laser effects to diverse technological fields. This book will prove useful to scientists interested in the physical phenomena of laser effects and engineers interested in practical applications of laser effects.

Book Synopsis Hydrodynamics of Evaporating Aerosols Irradiated by Intense Laser Beams by :
Download or read book Hydrodynamics of Evaporating Aerosols Irradiated by Intense Laser Beams written by and published by . This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis is presented describing the interactions of atmospheric aerosols with a high-intensity laser beam propagating along an atmospheric path. For the case of moderate beam irradiances, diffusive mass transport and conductive energy transport dominate the aerosol-beam interactions. In this regime, the coupled aerosol-beam equations are solved numerically to obtain the spatic-temporal behavior of the propagating beam, and of the irradiated aerosols. For higher beam irradiances, convective transport of mass, energy and momentum away from the irradiated aerosols must be considered. The hydrodynamic equations are solved in the surrounding medium for this regime subject to appropriate ''jump conditions'' at the surface of the irradiated aerosol. Numerical examples illustrative of both regimes are given for the case of irradiated water aerosol droplets. 11 refs., 6 figs.

Book Synopsis Variability of Air Temperature and Atmospheric Precipitation in the Arctic by : Rajmund Przybylak
Download or read book Variability of Air Temperature and Atmospheric Precipitation in the Arctic written by Rajmund Przybylak and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been known at least since the end of the century that the polar areas play a very important role in the formation of the Earth’s climates. It is also known today that they are the most sensitive regions to climatic change, and are thus perfect case studies for the detection of such changes. The most serious obstacle to the study of climatic and other geographical elements of the polar areas (including the Arctic) has always been the severe climatic conditions which prevail in these regions. Because of these extreme con- tions, research into particular elements of the climatic system (including the atmosphere) began here much later than it did in lower latitudes. For instance, the whole area of the Arctic was not sufficiently covered with a network of meteorological stations until the late 1940s (and even then there were large areas of the central Arctic and the Greenland interior for which no data were available). This is probably why it was not until the start of the 1990s that a body of work began to appear which analysed in any depth climatic variability for the Arctic as a whole. While a considerable number of papers had been p- lished before this period, most of them were local studies presenting highly localised information, providing air temperature measurements but often little else.
