Book Description
The indium arsenide-phosphide alloy system has been studied. Indium arsenide and indium phosphide compounds were prepared by pulling and directional freezing respectively. The InP ingots were characterized for distribution coefficients and electrical properties. Ingots of InAs(1-x)P(x) were pulled by two modifications of the Czochralski technique--an all-quartz sealed system and pulling through a liquid encapsulant. The two methods are compared and the latter found to be superior for these alloys. Electrical, X-ray and mass spectrometric measurements were made on the alloy ingots. Laser diodes were fabricated in a similar manner to those reported on previously, with power outputs up to 0.5W at 1.06 micrometer with better than 1% efficiency being obtained under pulsed conditions close to 100K. Amplification of the 1.06 micrometer emission from an InAs(1-x)P(x) laser diode was demonstrated in a Nd-doped glass fiber, showing a system gain of 50,000. (Author).

Book Description
Industrial Applications of Lasers focuses on how lasers have been used for practical applications in industry. This text aims to stimulate the imagination of the readers, who can then evaluate the potential application of lasers to solve their own problems. Comprised of 21 chapters, this book starts with an overview of the fundamental background of lasers, and then discusses the basic principles of how lasers operate. Other chapters provide an understanding of how holograms really work. This text also discusses several topics relevant to lasers, themselves, including the types of practical lasers and laser properties. This book considers laser safety, which is very important for anyone considering a laser application. Finally, this text explores the various developed laser applications, including scribing of ceramics, laser welding and cutting of metals, as well as applications in surveying, alignment, and metrology. This book is a valuable resource to laser technicians, physicists, scientists, researchers, and readers whose interests span a variety of fields.
