    Finally, fiber lasers have high wallplug efficiency (the conversion of input electrical energy into laser light) compared to CO 2 and solid-state lasers, and can also have low maintenance requirements. This lowers cost of ownership. The Pentagon’s laser weapon programs are multiplying in the wake of continued advances in high-energy solid-state lasers, encouraging results from field trials, and the appointment early this year of former NASA administrator Mike Griffin as undersecretary of defense for research and engineering.

    High-pulse-energy applications In general, good SWaP characteristics are beneficial for laser sources but are especially important for military, defense, aerospace, and remote sensing applications. Within these areas, specific applications that can benefit from high-pulse-energy air-cooled low-SWaP lasers include: Raman spectroscopy.   The damage threshold of a gas medium for nanosecond lasers is normally >1 kJ/cm 2 (ref. 15), which is two orders of magnitude higher than the operating laser energy flux of conventional solid Author: Yurina Michine, Hitoki Yoneda.

The High Energy Liquid Laser Area Defense System (HELLADS) is a US defence programme to develop a high-energy laser-based weapon system to defend against surface-to-air threats. The programme aims to develop a kW laser system to counter ground threats such as rockets, artillery and mortar (RAM), and surface-to-air missile attacks.

Hansen Laboratories of Physics.; United States. National Aeronautics and Space Administration.]. Recent progress in the development of highly efficient coherent optical sources was reviewed. This work has focused on nonlinear frequency conversion of the highly coherent output of the non-planar ring laser oscillators developed earlier in the program, and includes high efficiency second harmonic generation and the operation of optical parametric oscillators for wavelength diversity and tunability.

HIGH ENERGY EFFICIENT SOLID =ATE LASER SOURCES I. Introduction. The objective of this program is to perform basic research and to develop technology for solid state lasers for remote sensing and communication applications.

Our recent efforts have been concentrated on the refinement of the high-stability diode-pumped. This paper describes a high-energy laser (HEL) concept based on a disk-type solid-state laser operating in active mirror mode.

The Space Based Laser (SBL), Advanced Tactical Laser (ATL) and Large Aircraft Infrared Countermeasures (LAIRCM) programs promise even greater applications for laser weapons.

This book delves deeply into the real-world technologies behind the ‘directed energy weapons’ that many believe exist only within the confines of science fiction.

On the contrary, directed energy weapons such as high energy lasers are very real, and this book provides a crash course in all theBrand: Springer International Publishing.

The performance of a gas-cooled multislab laser is recently reported from the DiPOLE project within the Central Laser Facility (CLF RAL STFC), UK. The development is aiming at an efficient high pulse energy diode-pumped solid-state laser (DPSSL) architecture based on cryogenic gas-cooled, multislab ceramic Yb:YAG amplifier by: 1.

Introduction. Solid-state lasers (SSL) are attractive sources of coherent radiation for various scientific as well as industrial applications. As was mentioned in Chapter 2, lasers can be divided into five groups: solid-state, semiconductor, liquid, gas, and plasma lasers.

Introduction. High energy and high power lasers have found wide usage in research and application including material processing, solid-state research, particle physics, and as drivers for other radiation sources such as X-ray (K-alpha) : G Travish, J.K Crane, A Tremaine.

Efficient energy storage for millisecond time intervals is unique to solid state lasers. Energy storage permits solid state lasers to serve as optical integrators. Low brightness optical pumps can be optically integrated and laser energy delivered in a high peak power and high brightness laser beam.

This capability of solid state lasers is a prime reason for their utility. The first innovation was the invention of the laser itself, a solid state Cr File Size: KB. Chapter 4 Fundamentals of Laser-Material Interaction and Application to Multiscale Surface Modification Matthew S.

High average-power free-electron lasers may be useful for pumping high peak-power solid-state laser-amplifiers.

At very high peak-powers, the pump source for solid-state lasers is non-trivial: flash lamps produce thermal problems and are unsuitable for materials with short florescence-times, while diodes can be expensive and are only available.
