Examines the nature of laser light. Topics include: (1) production and characteristics of laser light; (2) nine types of lasers; (3) five laser techniques including holography; (4) laser spectroscopy; and (5) laser fusion and other applications. (SK)

A judge for the physics projects for the 1979 International Science and Engineering Fair describes many of the more popular science projects. Projects described include the following: carbon dioxide and helium-neon lasers, reverse flame investigations, holography, construction of a magnetic bottle to confine plasma, and aerodynamic drag. (BT)

Describes a method for making holograms viewable in white light without the problem of vibrations. Presents diagrams which show the arrangement for construction, viewing procedures, and a device for generating holograms. A list of supplies is included. (RT)

Discusses laser demonstration for invoking interest in science, especially physics. Describes some examples, such as diffraction, scattering, expansion by diverging lens, internal reflection in a light pipe, and illumination through optical cable. Provides some practical hints for the demonstration. (YP)

Described is a demonstration of Snell's law using a laser beam and an optical fiber. Provided are the set-up method of the demonstration apparatus and some practical suggestions including "index matching" technique using vaseline. (YP)

Some innovative ideas and applications for new television technology are described in this tabloid format periodical. Most of these ideas support the periodical's contention that broadcast television is the most limited use of a developing television technology which has the capability of being a responsive medium and a valuable social tool and,…

Examines the use of holography in the art technology program of a junior high school. Characterizing holography as a valuable artistic experience and discovery experience and stressing the importance of student interest and involvement, the author discusses the necessary equipment for the project and includes two diagrams of a holographic setup.…

Describes: (1) two experiments using a laser (resonant cavity for light and pinhole camera effect with a hologram); (2) optical differaction patterns displayed by microcomputer; and (3) automating the Hall effect (with comments on apparatus needed and computer program used); and (4) an elegant experiment in mechanical equilibrium. (JN)

The author taught the first auto body repair course in the country that employed laser-accurate equipment. He states that having this equipment raised the placement rate of his graduates, made the learning environment more positive, and improved students' understanding of math and science. (CH)

Provides description of the initial creation of a regional union catalog containing 600,000 unique titles and 1.8 million physical items, the conversion of this database to interactive laserdisc, and the resultant advantages. Updates, costs, problems, and the application of laserdisc technology are discussed. (EJS)

The occupational implications, employment projections, and training opportunities of three growing fields are discussed: laser technology, fiber optics, and genetic engineering. (CT)

Provides information regarding the extra bands of color, termed supernumerary arcs, that sometimes accompany a natural rainbow. Several experiments are described that elucidate the phenomenon of supernumerary arcs, involving the illumination of a hanging water droplet with white light from a projector or monochromatic light from a helium-neon…

Describes a project on the application of the laser which aims to stimulate the interest of undergraduate students in applied physics and to demonstrate the interaction between light and ultrasonic waves by building a simple laser communication system. (SK)

Describes a simple apparatus for producing strip holograms with a number of slit-shaped exposures displaced along the vertical direction. The hologram maintains full horizontal parallax, but the slit aperture reduces the vertical viewing angle of the animated object. (Author/GA)

Reports that although excitation at 337nm is less than optimal, detection limits in the range 1-100pg/ml were found. Provides a calibration curve and results for seven organic compounds. (MVL)
