...that each of our Latin American neighbors is quite different from the other. In relation to Cuba, I am for the liberation of Cuba without firing a shot. I feel that it is wholly possible we soon will be able to shave Castro's beard by means of laser rays...
...York City Superintendent Calvin Gross [Nov. 15] appears to be a laser beam cutting into the Stygian morass called American education. If this is really true, I may be coaxed into returning to the classroom firing line as a teacher...
...remarkable potential of lasers (Light Amplification by Stimulated Emission of Radiation) nurtures many a heady scientific dream. Pure, one-color laser light can be focused down to a microscopic point, hot enough to burn through any material. It can make superaccurate measurements, and properly modulated, it can carry vast amounts of information. It may some day take the place of wires in the innards of computers. But all these promising applications are blocked at present by the built-in problems of existing lasers. Some of them demand costly and cumbersome power supplies; some give light of the wrong wave lengths...
...Tyco Laboratories, Inc. of Waltham, Mass., has developed a laser that seems to have the necessary simplicity. Invented by Drs. A. I. Mlavsky and L. B. Griffiths, it is a .02-in. cube of silicon carbide (carborundum), 4Two opposite sides are carefully polished, and electrodes are attached to antfcher two. When a weak direct current of electricity is passed through the cube, a thin line in its center glows with green-blue light. But this is not pure laser light. It is merely ordinary mixed-up light of varying frequencies. When the current passes a critical strength...
This is genuine laser light. And it comes from a simple rugged device that works at room temperature (no liquid helium to worry about) with no need for an expensive power source. The current demand could be supplied by flashlight batteries. Says Arthur J. Rosenberg, president of Tyco:' "We could put it in a box the size of a pack of cards, battery and all, and signal with it. It's as simple as that...
