This book was released on 2009 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main program objective was the development of a kilowatt class, cw Nd:YAG diode-laser-pumped solid-state laser (DPSSL) with quantum noise limited amplitude and phase, 24by7 operation capability and the ability to be repaired while in operation. The approach was a master-oscillator power-amplifier (MOPA) laser utilizing a series of zig-zag slab power amplifiers stages. We developed fiber amplifiers at the 200W level to generate power with high optical efficiency that can effectively extract energy from the power amplifier slabs. We also worked on the generation of high average power visible light by developing nonlinear optical materials with large apertures, low photo-refraction and minimal visible induced infrared absorption. The second objective was to develop a 1 joule, pulse-modulated, diffraction limited MOPA laser with less than 1 MHz line-width. A follow-on objective was frequency conversion to 1.5 or 2.0 microns for remote sensing applications. We demonstrated Yb:YAG slab lasers pumped with high brightness laser diodes. Supporting this project was the development of laser diodes operating in the 1.5 micron region for pumping of erbium doped laser hosts, and the synthesis of new low-loss polycrystalline laser host materials for in-band pumping into the upper laser level to improve the laser efficiency at eye-safe wavelengths. We developed orientation patterned Ga-As to frequency convert high peak power 1-micron radiation to eye-safe wavelengths in the mid-infrared for defense applications. The third objective, power scaling and determining the potential for phase-locking of ultra-fast laser systems for a wide range of sensing and machining applications, was demonstrated as well.

Book excerpt: A solid-state laser use and gain medium that is a solid, rather than a liquid such as dye lasers or a gas such as gas lasers. Semiconductor-based lasers are also in the solid state, but are generally considered separately from solid-state lasers. Generally, the active medium of a solid-state laser consists of a glass or crystalline host material to which is added a dopant such as neodymium, chromium, erbium, or other ions. Many of the common dopants are rare earth elements, because the excited states of such ions are not strongly coupled with thermal vibrations of the crystalline lattice (phonons), and the lasing threshold can be reached at relatively low brightness of pump. There are many hundreds of solid-state media in which laser action has been achieved, but relatively few types are in widespread use. Of these, probably the most common type is neodymium doped YAG. Neodymium-doped glass (Nd:glass) and Ytterbium-doped glasses and ceramics are used in solid-state lasers at extremely high power (terawatt scale), high energy (megajoules) multiple beam systems for inertial confinement fusion. Titanium doped sapphire is also widely used for its broad tunability. This book gathers new research in the field.
Download or read book The Potential of High average power Solid State Lasers written by J. L. Emmett and published by . This book was released on 1984 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: We discuss the possibility of extending solid state laser technology to high average power and of improving the efficiency of such lasers sufficiently to make them reasonable candidates for a number of demanding applications. A variety of new design concepts, materials, and techniques have emerged over the past decade that, collectively, suggest that the traditional technical limitations on power (a few hundred watts or less) and efficiency (less than 1%) can be removed. The core idea is configuring the laser medium in relatively thin, large-area plates, rather than using the traditional low-aspect-ratio rods or blocks. This presents a large surface area for cooling, and assures that deposited heat is relatively close to a cooled surface. It also minimizes the laser volume distorted by edge effects. The feasibility of such configurations is supported by recent developments in materials, fabrication processes, and optical pumps. Two types of lasers can, in principle, utilize this sheet-like gain configuration in such a way that phase and gain profiles are uniformly sampled and, to first order, yield high-quality (undistorted) beams. The zig-zag laser does this with a single plate, and should be capable of power levels up to several kilowatts. The disk laser is designed around a large number of plates, and should be capable of scaling to arbitrarily high power levels.

This book was released on 2019-12-30 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in High-Power Fiber and Diode Laser Engineering provides an overview of recent research trends in fiber and diode lasers and laser systems engineering. In recent years, many new fiber designs and fiber laser system strategies have emerged, targeting the mitigation of different problems which occur when standard optical fibers are used for making high-power lasers. Simultaneously, a lot of attention has been put to increasing the brightness and the output power of laser diodes. Both of these major laser development directions continue to advance at a rapid pace with the sole purpose of achieving higher power while having excellent beam quality. The book begins by introducing the principles of diode lasers and methods for improving their brightness. Later chapters cover quantum cascade lasers, diode pumped high power lasers, high average power LMA fiber amplifiers, high-power fiber lasers, beam combinable kilowatt all-fiber amplifiers, and applications of 2 μm thulium fiber lasers and high-power GHz linewidth diode lasers. Written by a team of authors with experience in academia and industrial research and development, and brought together by an expert editor, this book will be of use to anyone interested in laser systems development at the laboratory or commercial scale.
Download or read book High Average Power Diode Pumped Solid State Lasers for CALIOPE written by and published by . This book was released on 1994 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diode pumping of solid state media offers the opportunity for very low maintenance, high efficiency, and compact laser systems. For remote sensing, such lasers may be used to pump tunable non-linear sources, or if tunable themselves, act directly or through harmonic crystals as the probe. The needs of long range remote sensing missions require laser performance in the several watts to kilowatts range. At these power performance levels, more advanced thermal management technologies are required for the diode pumps. The solid state laser design must now address a variety of issues arising from the thermal loads, including fracture limits, induced lensing and aberrations, induced birefringence, and laser cavity optical component performance degradation with average power loading. In order to highlight the design trade-offs involved in addressing the above issues, a variety of existing average power laser systems are briefly described. Included are two systems based on Spectra Diode Laboratory's water impingement cooled diode packages: a two times diffraction limited, 200 watt average power, 200 Hz multi-rod laser/amplifier by Fibertek, and TRW's 100 watt, 100 Hz, phase conjugated amplifier. The authors also present two laser systems built at Lawrence Livermore National Laboratory (LLNL) based on their more aggressive diode bar cooling package, which uses microchannel cooler technology capable of 100% duty factor operation. They then present the design of LLNL's first generation OPO pump laser for remote sensing. This system is specified to run at 100 Hz, 20 nsec pulses each with 300 mJ, less than two times diffraction limited, and with a stable single longitudinal mode. The performance of the first testbed version will be presented. The authors conclude with directions their group is pursuing to advance average power lasers. This includes average power electro-optics, low heat load lasing media, and heat capacity lasers.
