Discusses the principles behind holograms: the design and procedure to make either a reflection hologram or a transmission hologram, developing the hologram, safety precautions, and classroom applications. (JRH)

Laser refractometry is a science-technology-based activity that requires students to manipulate a variety of equipment, tools, materials, and critical-thinking skills. Students use a laser to measure the percent of glucose in a solution by calibrating the system, taking measurements, and computing the concentration. (MKR)

Presents both a geometric model of the hologram and a step-by-step guide to the procedures involved in making a hologram. (Author/CP)

This guide outlines the competency-based, two-year precision optics curriculum that the American Precision Optics Manufacturers Association has proposed to fill the void that it suggests will soon exist as many of the master opticians currently employed retire. The model, which closely resembles the old European apprenticeship model, calls for 300…

This second of two articles on photobiology focuses on clinical applications of light. See SE 511 547 for the first article. (DT)

Reviews recent developments in the study of an ultrafast process which utilizes short flashes of light. (SL)

Reviews recent developments in the field of laser fusion. (SL)

A massive concrete "waffle," riding on a bed of specially treated gravel and sand inside another building, provides the structural rigidity needed by the University of Rochester's Laboratory for Laser Energetics. (Author)

Presents a derivation of the minimum possible bandwidth of a laser oscillator. (SL)

Describes three elementary optics experiments using a laser instead of conventional light sources. Experiments illustrate the Fresnel-Arago law, elliptical polarization, double refraction and polarization in calcite, and interference by a Fresnel biprism. Because of the high intensity of the laser beam, these experiments lend themselves very well…
