The monochromaticity, directionality, and intensity of laser light make possible spectroscopic investigations of previously unimagined precision. Several of these investigations and their applications are discussed. (Author/JN)

Discusses advances in optics research including the role of lasers and high-speed computers, image processing, medical imagery, and classical optics. (JN)

Polarization of laser light is discussed and the theoretical and experimental aspects of fluxes are considered. (Author/SK)

A compact disc (CD) serves as a diffraction grating for the study of the dependence of angles of diffracted beams on that of the incident beam from a laser. The demonstration/experiment illustrates the occurrence of different orders of diffraction. Knowledge of the wavelength of the laser permits determination of the groove spacing within ~1% by…

A novel apparatus that strengthens the connection between research and teaching laboratories and serves multiple purposes is described. A versatile laser apparatus suitable for the undergraduate teaching laboratory that may serve as polarimeter, nephelometer or fluorimeter is designed.

Deals with the subject of laser hazards, laser hazards control, and laser safety practices in the laboratory. Describes four categories of hazards: radiative, electrical, explosive, and toxic, and explains the status of federal regulations that seek to define lazer hazards and control safety standards. (Author/GS)

The project described demonstrated not only the feasibility of producing a holographic compound spherical beamspliter mirror with full color response, but the performance and color capabilities of such a beamsplitter when incorporated into a Pancake Window Display system as a replacement for the classical glass spherical beamsplitter. This…

This booklet is one of the booklets in the "Understanding the Atom Series" published by the U. S. Atomic Energy Commission for high school science teachers and their students. Basic information for understanding the laser is provided including discussion of the electromagnetic spectrum, radio waves, light and the atom, coherent light, controlled…

Reviews the areas of laser chemistry, photochemistry, infrared lasers, and laser induced molecular reactions. (SL)

Reviews recent developments in the fields of ultraviolet lasers and rare gas lasers. (SL)
