Experimental data, Federal and State regulations, and user data are presented to assess the safety factors of low-power lasers. General safety precautions, basic laser theory, the place of the laser in the classroom, and some introductory exercises are also presented. (Author/TS)

Discusses the nature and applications of mass-selective laser photoionization. The ionization can be done with a single intense laser pulse lasting a few billionths of a second with no molecular fragmentation. Applications focus on: (1) benzene clusters, excimers, and exciplexes; (2) metal clusters; and (3) triplet formation and decay. (Author/JN)

Presents an overview of the construction techniques of dye lasers suitable for student projects and briefly describes possible laboratory projects. (JN)

Describes several different philosophies of mind with each philosophy's explanation of the mind-body problem. Philosophies discussed include dualism, materialism, functionalism, radical behaviorism, logical behaviorism and central-state identity. (DS)

Describes a physics exercise designed for biology and premed majors. The activity is a low intensity laser light scattering laboratory exercise to determine the diameter of micron-sized latex spheres (simulated microbes) in water suspension. (GA)

Described are three experiments on the photometric, Gaussian, and image-forming properties of a helium-neon gas laser. Details of the experimental method and typical calculations with diagrams and graphs are provided. (YP)

Explains the problem of analyzing a phase object, separating the contribution due to thickness variations and that due to refractive index variations. Discusses the design of an interferometer and some applications. Provides diagrams and pictures of holographic images. (YP)

Describes an experiment in which two semi-transparent reticles and a photographic plate separated by several centimeters are illuminated by a monochromatic point source in a typical in-line configuration that results in a hologram that contains information from both reticles. (Author/WRM)

Describes a technique in which a Fabry-Perot etalon can be used to demonstrate longitudinal and transverse modes present in a laser beam. (Author/CP)

This project was conducted to determine the vocational, technical, and scientific skills and knowledge needed to work with the fiber optics applications that are in all areas of technology. A research assistant was hired by the project director to collect data and develop a research base for the project. Information was gathered through a…

Developments in electronic technology that have improved and linked together telecommunication and computers are discussed, as well as their use in instruction, implications of this use, and associated issues. The first section briefly describes the following developments: microcomputers and microprocessors, bubble memory, lasers, holography,…

Describes the apparatus and procedures for conducting a simple speed of light experiment in an average laboratory using a laser source, a rotating mirror, and an oscilloscope. (SL)

This annotated bibliography contains citations for over 70 recently published journal articles, reports, and monographs on the subject of optical disks. Items are arranged alphabetically by author with annotations plus additional notes where appropriate. (CLB)
