...appeared as a mere spot of red light flashed last week on a screen. But scientists of Bell Telephone Laboratories at Murray Hill. N.J. are sure their new gadget, called a maser. from which the light came, will lead to astonishing things. The waves of red light moved exactly in step; other light is helter-skelter. The waves kept to the same razor-edged frequency; other light is a mixture of frequencies. They formed a slender pencil beam that hardly spread out at all. If they had marched to the moon-240,000 miles-they would have covered less than...
...heart of the Bell optical maser is a rod of synthetic ruby ½ in. in diameter and 1½ in. long. It is chiefly aluminum oxide, but atoms of chromium replace a small amount of the aluminum, and these atoms cause the maser action...
...Mile Beam. The light comes in short bursts a few millionths of a second apart, and they make a flash that lasts less than a thousandth of a second. But the light is incredibly bright and concentrated. When Bell scientists set up the maser at Holmdel, N.J. and pointed its beam to hit the Murray Hill laboratory 25 miles away, the red flashes could be clearly seen with the naked eye, and they registered strongly on photomultiplier tubes. Bell Labs, whose primary interest is in communication, looks forward to perfecting long-reaching maser beams that could carry everything from telephone...
Closeup! (ABC, 10:30-11 p.m.). Bell & Howell Co.'s excellent documentary series now turns to Haiti, the French-speaking Caribbean nation uncomfortably situated between Castro's Cuba and Trujillo's Dominican Republic...
