Describes the operation of the nitrogen laser-pumped dye laser, and the continuous wave (CW) dye laser. (SL)

Harlan Smith, chairman of the University of Texas's Astronomy Department, discusses a mobile lunar laser ranging station which could help determine the exact rates of movement between continents and help geophysicists understand earthquakes. He also discusses its application for studying fundamental concepts of cosmology and physics. (Editor/RK)

Discusses various aspects of high technology: computers in cars, computer-assisted design and manufacturing, computers in telephones, video recorders, laser technology, home computers, job training, computer education, and the challenge to the technology teacher. (CT)

This article discusses the procedure, historical development, and applications of holography, and discusses the feasibility and value of implementing a unit or course of study of laser holography into an existing photography laboratory and curriculum. An equipment and supplies list, giving supplies and cost, is included. (CT)

Describes the outstanding achievement in each of 10 major engineering categories. These categories include synthetic fibers, nuclear energy, computers, solid state electronics, jet aircraft, biomedical engineering, lasers, communications satellites, the United States space program, and automation and control systems. (JN)

Reviews applications of laser methods to analytical problems, selecting examples from multiphoton ionization and fluorescence analysis. Indicates that laser methodologies promise to improve dramatically the detection of trace substances embedded in "real" matrices, giving the analyst a most powerful means for determining the composition of…

Describes the characteristics and operational problems of optical waveguides, and concludes that the wide use of optical communications can be expected if difficulties in commercial production of components can be eliminated. (CC)

Comparisons between three amplification systems of signals from photoelectric detectors are made. (RR)

Article describes nine He-Ne laser projects which have been successfully carried out by junior and senior electrical engineering students. (IR)

Explores the effects of library use on both capacitance and laser-optical videodisc systems and outlines proper cleaning, servicing, and storage techniques. The article is excerpted from "Conservation in the Library," a book edited by Susan Swartzberg. (Author/JJD)

The author discusses past contributions technology has made to society and ways it will contribute to society's future. Included in these areas are basic biological research, laser technology, information systems, and space technologies. (CT)

Describes how the use of tunable lasers in coherent Raman techniques allows spectra to be taken for samples in which spontaneous Raman scattering is intrinsically weak. (MLH)

This article describes the basic physics of several types of holograms and discusses different recording materials in use. Current and possible future applications of holograms are described as well as their large-scale production. (Author)
