Mary Romano MarksThe latest entry in the Facts On File Science Sourcebooks series is a concise overview of lasers, their development, and uses. After explaining how a laser works, Billings examines the many types and how they are revolutionizing communications, surgery, dentistry, industry, the military, and scientific research. She also introduces researchers in the field of laser technology and describes how, in addition to improving the quality or efficiency of many ordinary tasks, lasers are being utilized to measure distance and motion, map, and more. The basic principles of lasers are presented in a straightforward fashion, with black-and-white photos and diagrams used to illustrate terms and theories. The implications of the technology for the future are only briefly discussed, but students will still find the text a helpful and accessible source. A glossary and a reading list are appended.
