Ever since lasers-a word and an instrument stemming from Light Amplification by Stimulated Emission of Radiation-were first perfected, their fierce, pure gleam has been one of the most revolutionary tools of advancing science. By stimulating the atoms of a synthetic ruby with brief bursts from a powerful strobe lamp, scientists demonstrated that they could produce spurts of "coherent" light -pure red light that is all of the same wavelength, all polarized in the same direction, and all traveling in phase in almost perfectly parallel beams. Such light can be focused so sharply that its energy is concentrated...
Blue Puff. Physicist Kiyo Tomiyasu, 42, technical director of General Electric Co.'s laser lab, is particularly proud of the ease with which one of his lasers has drilled holes in a pea-sized black synthetic diamond. Diamonds, which are the hard est things known to man, have been drilled before, but the process is difficult and time consuming. Dr. Tomiyasu (Nevada-born; Harvard doctorate) did the job on his diamond with laser light. Each hole was drilled by a flash that lasted only one two-thousandth of a second. Pinpointed by a lens on the crystallized carbon...
...Tomiyasu and his colleagues have also learned how to make laser light carry information. Modulated in much the same manner as radio waves, its high frequencies can handle far more intelligence than any microwave beam. Each five-thousandth-of-a-second burst of light can theoretically be made to transmit coded information that would be the equivalent of 200,000 words...
