Book Description
This book, now in its fourth edition, is a well-known classic on the ultrafast nonlinear and linear processes responsible for supercontinuum generation. The book begins with chapters reviewing the experimental and theoretical understanding of the field along with key applications developed since the discovery of the supercontinuum effect. The chapters that follow cover recent research activity on supercontinuum phenomena, novel applications, and advances achieved since the publication of the previous edition. The new chapters focus on: filamentation in gases, air, and condensed media; conical emission by four-wave mixing and X-waves; electronic self-phase mechanism; higher harmonics generation; attosecond laser pulses; complex vector beam supercontinuum; higher order self-phase modulation and cross-phase modulation; nonlinear supercontinuum interference in uniaxial crystals; new nonlinear microscopes involving supercontinuum and ultrafast lasers with biomedical applications; and other current supercontinuum applications in communications. The Supercontinuum Laser Source is a definitive work by one of the discoverers of the white light effect. It is indispensable reading for any researcher or student working in the field of ultrafast laser physics.

Book Description
Biophysics is a rapidly-evolving interdisciplinary science that applies theories and methods of the physical sciences to questions of biology. Biophysics encompasses many disciplines, including physics, chemistry, mathematics, biology, biochemistry, medicine, pharmacology, physiology, and neuroscience, and it is essential that scientists working in these varied fields are able to understand each other's research. Comprehensive Biophysics, Nine Volume Set will help bridge that communication gap. Written by a team of researchers at the forefront of their respective fields, under the guidance of Chief Editor Edward Egelman, Comprehensive Biophysics, Nine Volume Set provides definitive introductions to a broad array of topics, uniting different areas of biophysics research - from the physical techniques for studying macromolecular structure to protein folding, muscle and molecular motors, cell biophysics, bioenergetics and more. The result is this comprehensive scientific resource - a valuable tool both for helping researchers come to grips quickly with material from related biophysics fields outside their areas of expertise, and for reinforcing their existing knowledge. Biophysical research today encompasses many areas of biology. These studies do not necessarily share a unique identifying factor. This work unites the different areas of research and allows users, regardless of their background, to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding The field of biophysics counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Biophysics fills this vacuum, being a definitive work on biophysics. It will help users apply context to the diverse journal literature offering, and aid them in identifying areas for further research Chief Editor Edward Egelman (E-I-C, Biophysical Journal) has assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource

Book Description
"Over the past decade, revolutionary progress has been realized in ultrafast optics which is opening the door to exciting opportunities ranging from optical physics to cutting-edge optical engineering. Motivated by this research frontier, we have developed a multi-wavelength femtosecond optical system operating in the UV, visible, near-IR and mid-IR and have solved a variety of interesting challenges. Driven by the increasing industrial demands for scalable and robust femtosecond sources, an Yb:fiber master-oscillator-power-amplifier (MOPA) operating at 1.3 W, 1035 nm, 240 fs, 40 MHz is built. As the potential solution for non-invasive vision correction at an eye-safe wavelength, we report the first demonstration of micro-machining of ophthalmic hydrogels employing an Yb:fiber laser. The advent of photonic crystal fibers (PCFs) and supercontinuum generation (SC) has greatly expanded the wavelength scalability of laser sources. To address the limitations in spectral efficiency and coherence degradation of conventional SC, we demonstrate an efficient, low noise and robust femtosecond 1.3 [mu]m source based on the two zero dispersion wavelength (TZDW) PCF. Its excellent coherence property is measured for the first time employing an unbalanced Michelson interferometer we built. Motivated by emerging applications in the mid-IR molecular 'fingerprint' region, we report a novel scheme of femtosecond mid-IR generation based on frequency down-conversion from the TZDW source which successfully circumvents the energy constraints in prevalent Raman soliton based sources. With its wavelength limited to ~5.5 [mu]m, an improved self-phase modulation enabled tunable mid-IR system is demonstrated and its broad operating wavelengths of 4.2 - 9 [mu]m is validated by the Czerny-Turner mid-IR spectrometer we built. Laser projection display plays an important role in the display industry thanks to its large color gamut, small source étendue and high wall-plug efficiency. A novel speckle-free red-green-blue (RGB) source is demonstrated in a power-scalable manner which covers 192% NTSC color gamut (CIE 1976). To circumvent the shared issue in beam distortion of frequency converted visible sources, a telecentric projection illumination design based on liquid crystal on silicon (LCoS) is reported. Finally, a femtosecond UV source is constructed via external frequency tripling from the MOPA. The completed multi-wavelength optical system is synchronized and studied for applications including UV/mid-IR dual color imaging and black-light generation"--Pages vii-viii.

Book Description
In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.
