Book excerpt: This report describes the design, construction and characterization of a 2 dimensional micro laser array. The micro laser array consists of a monolithic pump array, microlenses, and a solid state gain module. Passive q-switching on a single element was also demonstrated on this program. The array produced 0.35 Watts of average power with an optical efficiency of 5.8%. 70 elements out of the 108 total elements were lasing and the best elements were lasing at 2 microJ energy per pulse and with 12% optical efficiency. The diode array pump was a TRW built, high power surface emitting array, HPSEA, device cooled by a TRW built micro channel heat exchanger. The gain material was 400 micron thick Nd:YVO4 and the output wavelength was 1.064 microns. The far field divergence of the entire array was 10.4 mrad and 3.5 mrad for a single element. Each of the elements in the array operated single longitudinal and single transverse mode. The frequency variation over the entire array was 43 GHz and was due to individual variations in cavity lengths.

Book excerpt: This Center-of-Excellence grant has two components: Development of an imaging, system based on microlaser arrays forms a central project among a group of laser diagnostic and therapeutic efforts primarily funded outside the grant. In year 2 we have dealt with the slow delivery of new microlaser array approach to the idea of all-solid-state confocal microscopy. One solution was moderately successful, and another has produced the first microscope that is electronically switchable from confocal to non-confocal. We think this may be a useful alternative to the final design. This report thus discloses patentable material. We describe first the central Microlaser Microscope project, then we will tough briefly on the other projects of the Center. Publications are primarily those of the smaller projects, though no longer exclusively so. The appendix includes some of the publications.

Download or read book Hybrid Organic Inorganic Perovskites Physical Properties And Applications In 4 Volumes written by and published by World Scientific. This book was released on 2022-01-07 with total page 867 pages. Available in PDF, EPUB and Kindle. Book excerpt: This four-volume handbook gives a state-of-the-art overview of hybrid organic inorganic perovskites, both two dimensional (2D) and three dimensional (3D), from synthesis and characterization and simulation to optoelectronic devices (such as solar cells and light emitting diodes), spintronics devices and catalysis application. The editors, coming from academia and national laboratory, are known for their didactic skills as well as their technical expertise. Coordinating the efforts of 30 expert authors in 21 chapters, they construct the story of hybrid perovskite structural and optical properties, electronic and spintronic response, laser action, and catalysis from varied viewpoints: materials science, chemical engineering, and energy engineering. The four volumes are arranged according to the focus material properties. Volume 1 is focused on the material physical properties including structure, deposition characteristic and the structure of the electronic bands and excitons of these compounds. Volume 2 covers the hybrid perovskite optical properties including the ultrafast optical response, photoluminescence and laser action. Volume 3 contains the spin response of these compounds including application such as spin valves, photogalvanic effect, and magnetic response of light emitting diodes and solar cell devices. Finally, and highly relevant to tomorrow's energy challenges, volume 4 is focused on the physics and device properties of the most relevant applications of the hybrid perovskites, namely photovoltaic solar cells. The text contains many high-quality colorful illustrations and examples, as well as thousands of up-to-date references to peer-reviewed articles, reports and websites for further reading. This comprehensive and well-written handbook is a must-have reference for universities, research groups and companies working with the hybrid organic inorganic perovskites.

Available in PDF, EPUB and Kindle. Book excerpt: Perovskite Materials and Devices A comprehensive overview of the important scientific and technological advances in commercialization of this important mineral Perovskite has held much interest for scientists and industrialists, as the mineral is abundantly available in nature. Due to the intriguing and unusual physical properties of perovskite materials—the high-absorption coefficient, low exciton-binding energy, and high dielectric constant, for example—there has been substantial focus on perovskite’s potential in applications. In particular, they have been of great use in sensors and catalyst electrodes, certain types of fuel cells, solar cells, lasers, memory devices, and spintronics, and as a result hold exciting opportunities for physicists, chemists, and material scientists alike. Perovskite Materials and Devices comprehensively covers all the milestone work in perovskites research, systematically introducing the properties, methods, and technologies associated with the mineral from fundamentals to promising applications to commercialization issues. The book focuses on traditional and novel electronic operations, such as solar cells, LEDs, lasing, photodetectors, X-ray detectors, transistors, and more. It also investigates ways to make the use of such materials more environmentally friendly, which in turn can make perovskite minerals more commercially viable. Perovskite Materials and Devices readers will also find Summaries of the latest state-of-the-art developments and technologies, such as perovskite nanocrystals and novel electronic devices Detailed discussion of organic/inorganic hybrid perovskites, all-inorganic perovskite CsPbX3, and lead-free halide perovskites Investigation of the photovoltaic applications, namely single-crystal devices, tandem cells, integrated devices, semi-transparent devices, and flexible devices Description of large-area module fabrication and stability investigating Perovskite Materials and Devices is a useful reference for materials scientists, solid state physicists and chemists, surface physicists and chemists, and electronic engineers. It is also an ideal resource for libraries that supply these fields.

This book was released on 2018-08-16 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transmission of large amounts of power in space by laser beam (diode lasers, in particular) requires an array of lasers to increase total power. Concentration of the beam requires some degree of coherence. Temporal coherence can be obtained by locking amplifiers to a master oscillator. However, spatial coherence is not so easily created or maintained. Many mechanical, thermal, and electrical factors oppose it continually. A very simple method is described for creating and maintaining a degree of spatial coherence by simply turning selected diodes ON or OFF. The degree of coherence can be chosen; the greater the coherence, the larger is the number of lasers required for a given power and the longer the lifetime of the array. An experiment for analyzing performance, verifying theory, and evaluating critical parameters is also proposed. Williams, M. D.

This book was released on 2011-12-02 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology has experienced a rapid growth in the past decade, largely owing to the rapid advances in nanofabrication techniques employed to fabricate nano-devices. Nanofabrication can be divided into two categories: "bottom up" approach using chemical synthesis or self assembly, and "top down" approach using nanolithography, thin film deposition and etching techniques. Both topics are covered, though with a focus on the second category. This book contains twenty nine chapters and aims to provide the fundamentals and recent advances of nanofabrication techniques, as well as its device applications. Most chapters focus on in-depth studies of a particular research field, and are thus targeted for researchers, though some chapters focus on the basics of lithographic techniques accessible for upper year undergraduate students. Divided into five parts, this book covers electron beam, focused ion beam, nanoimprint, deep and extreme UV, X-ray, scanning probe, interference, two-photon, and nanosphere lithography.
