Available in PDF, EPUB and Kindle. Book excerpt: The four-wave mixing interaction proposed for uv frequency shifting cannot be phase matched with known techniques. One related process that avoids phase matching problems is stimulated Raman scattering (SRS). The same wavelength generated by four-wave mixing (2821 A) could also be generated by SRS using the uv pump source alone. In this case, the uv pump power must be high enough to exceed the oscillation threshold. SRS was observed in liquid CO pumped by the doubled Nd:YAG laser at 5320 A. The quadrupled Nd:YAG pump power at 2660 A was insufficient to attain SRS threshold. Although high-efficiency SRS should be attainable in the uv with more pump power, it is unlikely that this process can compete with frequency shifting of a KrF laser by SRS in hydrogen. The materials examined for Raman shifting of 10 .mu.m lasers show promise for efficient energy conversion to the 16.mu.m region. However, a more quantitative evaluation must await further data on Raman cross section and linewidth. In the case of fibers, some further materials development work is also required.

Download or read book Single Frequency Fiber Lasers written by Zhongmin Yang and published by Springer. This book was released on 2019-02-19 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a contemporary overview of the technologies of single-frequency fiber lasers. The development of single-frequency fiber lasers is one of the most significant achievements in the field of laser photonics over the past two decades. Owing to the crucial demands of a laser sources with highly stable single-frequency operation, narrow linewidth, low noise, scalable to high output power, compact and robustness structure, fiber lasers have been intensively studied since its introduction to the single-frequency laser community and they still continuously proceed to trigger the emergence of new technologies and applications. This book systematically demonstrates the single-frequency fiber laser technologies from fundamental principles to state-of-the-art progress. Details of selected typical applications of single-frequency fiber lasers are also given and discussed. The reader will acquire a good knowledge of the current situation within this important field.

This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
