Download or read book Orthogonal Polarization in Lasers written by Shulian Zhang and published by John Wiley & Sons. This book was released on 2013-08-14 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers generally emit radiation, which is either simply linearly polarized or unpolarized and stochastically polarized. Contrary to these common lasers, all orthogonally polarized lasers simultaneously emit radiation in two linear polarization states, both exactly orthogonally oriented to each other. Due to this orthogonality, both polarized components in the beam are independent of each other to a high degree and the studies presented in this book make clear that this feature can give a strong advantage in certain laser applications, for instance in high-precision measurements. Orthogonal Polarization in Lasers: Physical Phenomena and Engineering Applications summarizes the basics and advanced research results of orthogonally polarized lasers, birefringence laser cavities, and their applications. The authors include a number of figures, experimental designs, and measurement curves to enable the reader to not only learn the basic principles and technologies but also to understand many applications in modern engineering and to start their own R&D projects. The book covers polarization effects, which are of fundamental importance across various disciplines of science and technology. Includes a number of figures, experimental designs, and measurement curves to help readers learn the basic principles and start their own R&D projects. Discusses many types of relevant lasers (helium/neon lasers, ND:YAG lasers, semiconductor lasers, laser diodes). Written by multiply-published authors in the subject area. Contains material useful for metrology applications. This book is intended for use by researchers, postgraduates, and engineers working in laser science, optics, and measurement and testing, while senior undergraduate students working in optical and laser science can use the book for advanced understanding in their field.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of the latest research on the science, technology, and applications of mode-locked fiber lasers generating pulse trains with the evolving state of polarization at time scales ranging from a few pulse widths to 10,000 laser cavity round-trip times. It supports readers with a timely source of information on the current novel scientific concepts, and cost-effective schematics, in addition to an overview of the feasible applications. The book aims to demonstrate for the nonlinear science community a newly emerging field of nonlinear science, and so stimulates the development of new theoretical approaches and opens new horizons for the photonics community by pushing boundaries of the existing laser systems towards new applications. The new classes of optical sources and photonic devices explored in this book will be relevant with applications to other fields, including medicine, bio-photonics, metrology, and environmental safety. Key Features • Provides a cutting edge review of the latest emerging science, technology and applications in the field. • Tackles a topic with fast growing interest in USA, Europe and China. • Explores the simple and cheap design and tests of lasers, and outlines the feasible applications.

This book was released on 2018-07-10 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The LP-140 is a commercial pulsed CO2 laser system. An attempt was made to convert this workhorse laser into a device suitable for coherent LIDAR applications. This required initial laser characterization, and system modification. The key changes which enabled the laser to display encouraging characteristics are: increased cavity length; increased gas flow; gas mixture modification; and power supply redesign. With suitable modifications, the LP-140 becomes a viable candidate for a coherent LIDAR. Jaenisch, H. M. Unspecified Center...
Download or read book Stress Effect on Polarization of Surface Emitting Lasers written by T. Mukaihara and published by . This book was released on 1992 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: For polarization-sensitive applications such as magneto-optic disks and coherent detection systems, the polarization state of surface emitting (SE) lasers must be well defined. From the measured polarization characteristics, it was found that the output of mesa-structure SE lasers were linearly polarized and homogeneous lasers were unstable in terms of polarization state. Several polarization control methods were also suggested. However, the stress would affect the polarization state of SE lasers and it is necessary to clarify its effect for stable polarization control. We have investigated the lasing mode of SE lasers with the elliptical etched well. This elliptical hole may produce an anisotropic stress in the active region induced by the asymmetric shape of the well. A model of SE laser with the anisotropic holed region is shown. The epitaxial layers are bent due to the difference of the thermal expansion coefficient between GaAs and AlGaAs. This provides the tensile stress difference between the major axis and the minor axis of the holed region. There are two cases, Type I and Type II which provide the differential gain along the major axis and the minor axis, respectively.
Download or read book The Effects of Optical Feedback on Polarization of Vertical Cavity Surface Emitting Lasers written by and published by . This book was released on 1993 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical Cavity Surface Emitting Lasers (VCSELs) are a type of semiconductor laser with a cavity oriented orthogonally to the planes of material growth. These lasers differ from conventional edge emitting lasers in several important ways. They have symmetric output beams and they are easily built into two dimensional arrays, making them very attractive as photonic components. The characteristic of interest in this thesis is polarization. While the asymmetric cavities of edge emitters exhibit a clear preference for light polarized in a particular direction, the cylindrically symmetric cavity of a VCSEL has no clear preference. Therefore, it should be relatively easy to change the polarization of a VCSEL. This thesis examines the polarization switching effects of optical feedback from an external reflector. By feeding back various amounts of cross-polarized light, the switching susceptibility of the VCSEL can be determined. Measurements confirmed that the polarization of a VCSEL can be switched through polarized optical feedback, with the degree of switching depending on the strength of feedback. This switching was a relatively rare behavior, indicating that most VCSELs had some type of preferential polarization. This preference could be due to the VCSEL structure itself or the manner in which it was excited.
