Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the report is to present a review of the atmospheric effects on laser propagation. Molecular absorption by the earth's atmosphere should not present an insurmountable problem for ruby or neodymium laser systems. However, both the water vapor and the carbon dioxide present in the atmosphere strongly absorb radiation at carbon dioxide wavelengths; this may present a serious problem to systems employing carbon dioxide lasers. Clean air scattering does not seem to be a serious problem. Aerosol scattering, however, is quite severe and will, except in the clearest weather, strictly limit the operation of ground-based laser communication systems. Atmospheric turbulence also poses a serious limitation on the performance of optical communication systems. However, on the basis of the presently available data it does not seem that atmospheric turbulence will necessarily render laser communication systems unfeasible. (Author).

This book was released on 1973 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of state-of-the-art meteorological or other systems applicable to the measurement of the atmospheric parameters that affect laser beam propagation is reported in this study. A concept of meteorological support initially envisioning instrumentation deployed in ground-based, balloon-borne, and aircraft-borne systems is developed. Various state-of-the-art techniques and instruments are discussed and compared, with recommendations being made as to the best technique or instrument for the initial system. Calculations of the range dependence of the signal-to-noise ratio for current state-of-the-art lidar systems are presented. An advanced system envisioning solely aircraft-deployed laser remote sensors is conceived. A program to develop improved meteorological instrumentation for airborne laser test is suggested which contains three areas: (1) the determination of those atmospheric parameters which most influence laser radiation; (2) the determination of the variability of these parameters; and (3) the development of remote sensing systems to measure the parameters.

Download or read book Effects of Particulate Matter on Atmospheric Propagation of CO2 Laser Radiation written by David C. Smith and published by . This book was released on 1973 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two main nonlinear propagation problems encountered by high power CO2 laser radiation in the atmosphere are gas breakdown and thermal blooming. The influence of particulate matter on gas breakdown and also on thermal blooming was investigated. Typical atmospheric conditions contain approximately 1000 particles/cc. The presence of these particles in the air path of a high power laser beam can dramatically influence the propagation of the beam. This is illustrated by a photograph which shows particles being vaporized and ionized by a high power pulsed CO2 laser beam. The plasma balls generated not only attenuate the laser radiation, but they also act as scattering centers with completely different scattering characteristics than the original particles. The hot vapor can also act as a thermal source which could cause self-induced thermal distortion of subsequent laser pulses.
