William L. Mcbrideld associated with a propagating electromagnetic wave (1–9). At low electric fields, there is a linear relationship with the susceptibility, χ., defining the proportionality constant. High fields can be created by focusing lasers to small areas where the fields become comparable to the binding force

Assen Ignatowod are discussed in detail. In a second part single-atom detection in the laboratory is reviewed, and as an example an experiment is presented in which collision processes of single atoms were studied..In the past decade the detection of small concentrations of atoms and molecules in the atmosphere

J. M. Bernstein one considers even such unlikely things as the Mössbauer effect and X rays. Within a very short period of their discovery, they had welI-formulated biological and medical applications. The discovery of the laser is no exception. AIthough the theoretical basis for it was established in 1917 by Einst

for the treatment of various eye diseases since the early 1950s. For centuries man has known that prolonged exposure of his eyes to the sun results in visual loss. With the development of the ophthalmoscope in the middle of the 19th century, the deleterious effects of the sun’s rays were seen to be

Tom Rockmore rate more rapid than even the most fanciful dreamers envisioned. Of course, the main effort has been on the laser itself-new wavelengths, shorter and longer time domains for pulses, increases in power, and, most important, greater reliability. In its first stage the laser was described as a solutio

ese are not new uses of lasers, but rather improvements of laser techniques already widely accepted in both research and clinical situations. Biological reactions to some special aspects of laser exposure continue to show new effects, which have implications for the ever-present topic of laser safet

Nicolas Tertulian result of the demand for ultraviolet wavelengths in the developing fields of laser photochemistry and photobiology, and to some extent the interest in materials processing and microfabrication. In part, it is a result of a natural tendency for the laser physicist to turn in a direction in which the
