A number of experiments carried out in the last two decades, have led to the development of lasers as the next generation weapon system. A number of defense companies are carrying out research in this field and have achieved varying degrees of progress in constructing a high energy weapon. Laser technology has observed great scientific developments and engineering improvements that make it usable for various commercial, industrial, medical and scientific applications. There is variety of lasers available in the market today with different wavelengths, spectral bandwidth, power levels, operating efficiencies and temporal characteristics. This increasing maturity of lasers and compact optical systems has enhanced their capabilities for military operations. Military officials have indubitably always been interested in laser technology, even before the first laser was invented. Especially, since these devices can bring technological revolution in warfare, when used as range- finders, target designation, sensors, active illumination, data relay devices, directed energy weapons, weather modifier and much more. Military Laser Technology and Systems presents comprehensive coverage in defense oriented research and development for the past twenty years, focusing primarily on applications of lasers for military systems. It provides an insight into the physical principles of the device technology that underpins many laser-based military systems in one form or another. From this knowledge a deeper understanding of the fundamental requirements and the potential performance, as well as limitations of such systems may be assessed, given the appropriate operational parameters. The task of this book is to focus the interests of laser physics community to the mono-module disk laser geometry, which is possible now for implementation. The experience of designing strategic laser systems in the previous years and a strong belief in the attainability of the goal in the development of high-power laser weapons help to significantly accelerate the pace of work in the field of new technologies. Brining solid-state lasers to megawatt powers takes time and considerable resources. This book will be of valuable to students and practicing engineers providing with practical study of laser applications, used by the military, to carry out tactical operations on the ground or space-based platforms.
