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)

Provides an alternative method of using water instead of a mirror to create a laser light show. (ZWH)

This laboratory training manual on laser communications and fiber optics may be used in a general technology-communications course for ninth graders. Upon completion of this exercise, students achieve the following goals: match concepts with laser communication system parts; explain advantages of fiber optic cable over conventional copper wire;…

Describes the construction of a flexible coupled-cavity interferometer for student use. A helium-neon laser and phonograph turntable are the main components. Lists activities which may be performed with the apparatus. (Author/CP)

Describes a set of experiments that uses a low-power gas laser to demonstrate difficult physical and mathematical concepts. (MLH)

Traces the development of stabilized lasers from the Massachusetts Institute of Technology passive-stabilization experiments of the early 1960s up through the current epoch of highly stabilized helium-neon and carbon dioxide and continuous wave dye lasers. (Author/HM)

Discusses the use of laser spectroscopy in determining the presence of specific gaseous constituents. Three of currently used modes for laser detection of pollution are reviewed; (1) long-path measurements; (2) laser raman (differential absorption) measurements; and (3) optoacoustic detection. (HM)

Describes a currently used picosecond spectroscopy system capable of reliably recording picosecond events. Two areas of picosecond research are discussed: one concerns the interaction of electrons in fluids; the second, the primary events in vision. (Author/HM)

The use of the Laser Cane with four blind students attending public school is discussed with emphasis on modifications in technique needed to integrate the cane's use into each student's travel system. (Author)

Describes a holographic method of producing a picture of a real lens, objects, and the virtual image of the objects. (SL)

Presents rudimentary theory for Resonance Raman Spectroscopy and examples of its application. (SL)

This special report shows some of the artistic results of a science and art collaboration in the materials research laboratory at Pennsylvania State University. This collaboration hopes to extend the dimensions of both worlds into new levels of awareness and thus develop new expressions of productivity. (BT)

Describes Drexon LaserCard (credit card size format holding two megabytes of digital data that can be recorded at factory or by information distributors) as a viable option to rotating optical media for distribution of computer software, technical manuals, periodicals, and other document applications, and projects its future in optical publishing.…

The increased expansion of laser technology will create many new jobs and will require workers with many different skills. At the same time, some kinds of occupations will be adversely affected, due to increasing use of laser technology in a broad range of industries. (CT)
