Available in PDF, EPUB and Kindle. Book excerpt: The US Navy is exploring the feasibility of using a high energy laser weapon as a ship-borne self-defense system against sea-skimming cruise missile attacks. Since the attenuation of laser energy by the atmosphere is the highest at low altitudes and varies with frequency, the selection of appropriate wavelengths becomes critical for a laser weapon to be effective. A high energy free electron laser (FEL) is suitable for employment in the envisaged role because it can be designed to operate at any desired frequency and, to a degree, is tunable in operation. This study aims to determine the optimal atmospheric windows for high energy, pico second, short pulse lasers. Computer simulations were carried out by convolving a pulse spectrum with the transmission spectrum and the absorption coefficient from the MODTRAN and FASCODE atmospheric codes. Transmission spectrum and absorption coefficient plots were compared to find the range of suitable wavelengths that give good transmittance and low absorption coefficient values.

Download or read book Plasma Production By Laser Ablation Ppla 2003 written by Lorenzo Torrisi and published by World Scientific. This book was released on 2004-10-12 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume concerns the latest results on pulsed plasma production by energetic laser pulses irradiating solid targets. The produced plasma emits neutrals, clusters, ions, electrons and photons. Plasma properties depend on the laser pulse duration, energy, wavelength, focusing, target nature and irradiation conditions. Plasma expands in vacuum with supersonic velocity and may accelerate heavy ions, with charge states higher than 50+, at energies higher than 10 MeV. This book presents and discusses possible applications, such as ion injection in ECR ion sources, ion implantation, ion post-acceleration and thin film deposition by the PLD technique.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences

Download or read book Handbook of Solid State Lasers written by B Denker and published by Elsevier. This book was released on 2013-02-20 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid-state lasers which offer multiple desirable qualities, including enhanced reliability, robustness, efficiency and wavelength diversity, are absolutely indispensable for many applications. The Handbook of solid-state lasers reviews the key materials, processes and applications of solid-state lasers across a wide range of fields.Part one begins by reviewing solid-state laser materials. Fluoride laser crystals, oxide laser ceramics, crystals and fluoride laser ceramics doped by rare earth and transition metal ions are discussed alongside neodymium, erbium and ytterbium laser glasses, and nonlinear crystals for solid-state lasers. Part two then goes on to explore solid-state laser systems and their applications, beginning with a discussion of the principles, powering and operation regimes for solid-state lasers. The use of neodymium-doped materials is considered, followed by system sizing issues with diode-pumped quasi-three level materials, erbium glass lasers, and microchip, fiber, Raman and cryogenic lasers. Laser mid-infrared systems, laser induced breakdown spectroscope and the clinical applications of surgical solid-state lasers are also explored. The use of solid-state lasers in defense programs is then reviewed, before the book concludes by presenting some environmental applications of solid-state lasers.With its distinguished editors and international team of expert contributors, the Handbook of solid-state lasers is an authoritative guide for all those involved in the design and application of this technology, including laser and materials scientists and engineers, medical and military professionals, environmental researchers, and academics working in this field. Reviews the materials used in solid-state lasers Explores the principles of solid-state laser systems and their applications Considers defence and environmental applications

Download or read book Tunable Lasers and Applications written by A. Mooradian and published by Springer. This book was released on 2013-06-29 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tunable Lasers and Applications Conference was held in Loen, Norway, on June 6-11, 1976. This conference dealt with the technology of tunable lasers from the vacuum ultraviolet to the far infrared and their application in the areas of photochemistry, chemical kinetics, isotope separation, at mospheric photochemistry and environmental studies, photobiology, and spec troscopy. The need for such a conference grew out of the rapidly expanding use of tunable lasers in a broad range of disciplines. The conference was attended by 130 scientists representing Japan, Italy, West Germany, Canada, Israel, France, England, Norway, Sweden, Brazil, Den mark, Finland, the Netherlands, the Soviet Union, and the United States. The location of the conference in Loen, Nordfjord, was chosen because of the magnificent beauty of its aqua-blue fjords surrounded by glacier-capped mountains and lush green hillsides. The Alexandra Hotel was a perfect host for such a conference with first class services, superb smorgesbord, and ex cellent audio-visual facilities. The atmosphere was free of distractions and provided for a relaxed interchange of ideas. An afternoon hike was arranged to the Briksdal glacier while the highlight of the outdoor activities was a bus-ship excursion to the magestically splendid Geiranger fjord. A sumptuous banquet was followed by an interesting'and entertaining illustrated talk on high-speed and underwater photography by Professor Harold Edgerton from MIT. Financial support from our sponsors is gratefully acknowledged in help ing to make this conference a complete success.

Download or read book Atmospheric Transmission Coefficients for Laser Pulses with Spectral Widths of a Few Tenths of a Nanometer Over the Wavelength Region from 800 to 860 Nanometers written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-16 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective atmospheric transmission spectra were calculated from 800 to 860 nanometers for laser sources with spectral widths of a few tenths of a nanometer. In this spectral region, the atmospheric absorption lines (water lines) have linewidths of a few hundredths of a nanometer, so that the transmission coefficient for a relatively wide laser pulse must be computed by taking a weighted average over the pulse spectral width. Laser spectral widths of several tenths of a nanometer are shown to reduce the effective absorption by water lines to as little as 10 to 20 percent, even when the laser is centered on a line or overlaps several lines. Thus, the effect of absorption by atmospheric water lines may be greatly reduced for laser communication systems using laser diode array transmitters, for which the pulse spectral width may be a few tenths of a nanometer.
