Although scarcely 20 years have passed since the creation of the first laser, laser engineering has enjoyed a variety of applications in science and in practice. Among these applications, a special pI ace is held by those related to the propagation of laser radiation in the atmosphere. Some, such as laser communication and information-transmission systems, locating and teleme tering systems, and mapping and navigation systems, require access to quantitative data on the effects of the atmosphere on the parameters of the laser beam serving as the carrier of useful information, since the efficacy of any such system depends significantly on the influence of the atmosphere. Another set of laser applications associated with the propagation of coherent radiation in the atmosphere requires the solution of both direct and inverse problems related to this complex subject. The kind of applica tion in question is the use of lasers for long-range monitoring of various physical parameters of the atmosphere-a new and highly promising direc tion in science and engineering.

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.

Atmospheric turbulence can affect the propagation of laser beams of any power. Thermal blooming, a nonlinear propagation process, can seriously degrade high-energy beams. These two processes are reviewed in detail, with emphasis on parametric effects such as aperture size wavelength, and focal distance. Included in the discussion are such new topics as supersonic slewing and stagnation zone problems. (Author).

This book deals with theoretical bases of the modern optics division concerned with coherent light fields with singularities characterized by phase uncertainty. Singular light fields include laser vortex beams or beams that carry orbital angular momentum. Laser vortex beams that have been introduced in optics in recent years are discussed in detail. Among them, of special notice are families of asymmetric laser vortex beams that, while being devoid of radial symmetry, remain unchanged upon propagation. What makes the laser vortex beams especially interesting is the ability to preserve their structure while propagating in a scattering medium or through a turbulent atmosphere. The orbital angular momentum is an extra degree of freedom of laser vortices because beams with different topological charge can be utilized as independent channels for data transmission in wireless communications. Laser vortex beams are generated from conventional Gaussian beams using liquid crystal light modulators, which are now readily available at any optical laboratory. Provide a framework for the comparative analysis of the efficiency of different vortex beams for micromanipulation. Includes detailed illustrations, enabling the vortex structure to be easily understood even by non-experts. Presents detailed descriptions of more than a dozen most popular types of vortex laser beams. Explores how optical vortices have been used in many practical applications including conventional and quantum wireless communications, micromanipulation, optical measurements with super-resolution, spiral interferometry, microscopy, and atom cooling. Presents in a systematic and detailed form many analytical and numerical results for the propagation vortex optical beams (chiefly in the linear propagation regime).
