Download or read book Birefringence and Bragg grating control in femtosecond laser written optical circuits written by and published by Luis Andre Fernandes. This book was released on 2012-12-31 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, femtosecond lasers are explored for the fabrication of fiber Bragg gratings (FBGs) in suspended core fibers (SCFs) as well as direct writing of integrated optical devices in bulk fused silica glass. The FBGs fabricated in suspended core fibers with different core geometries were demonstrated with femtosecond laser exposure through a Talbot interferometer. In this case, the use of a femtosecond laser system was crucial as it eliminates the need for the use of photosensitive fibers, which is the case for SCFs, while the Talbot interferometry setup provided flexibility in the definition of the grating periodicity, while simultaneously protecting the optical components used in the fabrication process from the high intensities reached during exposure in the proximity of the fibers. These Bragg gratings were employed to show simultaneous strain and temperature sensing. Using a femtosecond laser direct writing system, novel point-by-point fabrication arrangements, with detailed attention to the computer controlled laser beam modulation, were developed in order to correctly introduce modulation of the refractive index profile during the waveguide fabrication process. This technique enabled the development of phase and frequency control required for advanced Bragg grating waveguide (BGW) fabrication and arbitrary spectral shaping. Procedures were demonstrated for the fabrication of chirped and phased shifted BGWs for applications in temporal pulse shaping and spectral shaping that showed significantly improved feature resolutions for sensing applications. The BGWs were used as a practical sensitive tool to determine and study the waveguide birefringence inherent to the nonlinear absorption processes typical of femtosecond laser-material interaction. The control of form and stress birefringence was developed in order to accomplish the fabrication of integrated optical components for polarization control, like guided wave retarders and polarization beam splitters. Tuning of this waveguide birefringence was achieved by the introduction of stress inducing laser modification tracks that enabled the ability to both enhance or reduce the inherent birefringence. Characterization techniques were developed for the absolute determination of the birefringence based on BGWs spectrum splitting, together with crossed polarizer measurements, while novel data analysis procedures were demonstrated for the study of polarization dependent and polarization independent directional couplers with the introduction of a polarization splitting ratio which is wavelength and coupling length dependent. All of the improvements made in the understanding of waveguide birefringence control provided increased flexibility to simultaneously fabricate low polarization mode dispersion circuits, as well as more efficient and compact polarization dependent devices. The polarization aspects detailed here, together with the point-by-point fabrication system, may be further developed in the future towards the fabrication of more complex integrated devices that combine spectral, temporal, and polarization control, all achievable with the same femtosecond laser writing system. These flexible processing techniques will open new directions for writing additional functionalities in optical circuits with more compact three-dimensional geometries.

Download or read book Ultrafast Optics IV written by Ferenc Krausz and published by Springer. This book was released on 2012-08-10 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume cover the major areas of research activity in the field of ultrafast optics at the present time, and they have been selected to provide an overview of the current state of the art. The purview of the field is the methods for the generation, amplification, and characterization of electromagnetic pulses with durations from the pieo-to the attosecond range, as well as the technical issues surrounding the application of these pulses in physics, chemistry, and biology. The contributions were solicited from the participants in the Ultrafast Optics IV Conference, held in Vienna, Austria, in June 2003. The purpose of the conference is similar to that of this book: to provide a forum for the latest advances in ultrafast optical technology. Ultrafast light sources provide a means to observe and manipulate events on the scale of atomic and molecular dynamics. This is possible either through appropriate shaping of the time-dependent electrie field, or through the ap plication of fields whose strength is comparable to the binding forces of the electrons in atoms and molecules. Recent advances discussed here include the generation of pulses shorter than two optical cycles, and the ability to measure and to shape them in all degrees of freedom with unprecedented 2 21 2 precision, and to amplify them to the Zettawatt/cm (10 W /cm ) range.

Book excerpt: This book discusses aspects of laser pulses generation, characterization, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. The introductive chapter shortly overviews the physical principles of pulsed lasers operation with pulse durations from seconds to yoctoseconds. A theory of mode-locking, based on the optical noise concept, is discussed. With this approximation, all paradoxes of ultrashort laser pulse formation have been explained. The book includes examples of very delicate laser operation in biomedical areas and extremely high power systems used for material processing and water purification. We hope this book will be useful for engineers and managers, for professors and students, and for those who are interested in laser science and technologies.

This book was released on 2018-01-31 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laser has revolutionized many areas of science and society, providing bright and versatile light sources that transform the ways we investigate science and enables trillions of dollars of commerce. Now a second laser revolution is underway with pulsed petawatt-class lasers (1 petawatt: 1 million billion watts) that deliver nearly 100 times the total world's power concentrated into a pulse that lasts less than one-trillionth of a second. Such light sources create unique, extreme laboratory conditions that can accelerate and collide intense beams of elementary particles, drive nuclear reactions, heat matter to conditions found in stars, or even create matter out of the empty vacuum. These powerful lasers came largely from U.S. engineering, and the science and technology opportunities they enable were discussed in several previous National Academies' reports. Based on these advances, the principal research funding agencies in Europe and Asia began in the last decade to invest heavily in new facilities that will employ these high-intensity lasers for fundamental and applied science. No similar programs exist in the United States. Opportunities in Intense Ultrafast Lasers assesses the opportunities and recommends a path forward for possible U.S. investments in this area of science.

Download or read book Robotic Nondestructive Testing Technology written by Chunguang Xu and published by CRC Press. This book was released on 2022-09-26 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The content of this book includes a variety of nondestructive testing (NDT) methods, with many introductions to testing and application cases. The book proposes new ultrasonic testing technology for complex workpieces. It is hard for traditional NDT technology to realize the automatic detection of complex curved components, especially the automatic high-precision nondestructive detection of curved-surface components with variable curvature, variable thickness and complex contour. Therefore, the robotic NDT technique as a combination of manipulator technique and NDT technique can further improve the efficiency and accuracy of NDT. Robotic NDT Technique combines the physical principle of nondestructive testing with the flexible motion control of spatial attitude of articulated manipulator. With NDT as the constraint, it controls the motion attitude and azimuth angle of a transmitting and receiving transducer. Thus traditional NDT technique has developed from plane to curved surface, from 2D to many dimensions and from artificiality to intelligence, into a unique and systematic interdisciplinary robotic NDT technique.
