...flying missiles, like the cruise, that would not be vulnerable to space defenses. The satellites could also be vulnerable. "Many potential counters, such as decoys or space mines, have the power to neutralize space-based systems," says Stanford University Physicist and Arms Control Expert Sidney Drell. His colleague Arthur Schawlow, who won the Nobel Prize for his work on developing the laser, agrees: "A laser battle station out in space would be a sitting duck...
...Siegbahn, 63, of Sweden's Uppsala University, who follows in the footsteps of his late father Karl Siegbahn, the 1924 laureate in physics.* The other half of the award will be shared equally by two Americans, Nicolaas Bloembergen, 61, a Dutch-born Harvard professor, and Arthur Schawlow, 60, of Stanford. The prize in chemistry will go to Kenichi Fukui, 63, of Japan's Kyoto University, and Roald Hoffmann, 44, of Cornell University...
...atom or molecule stimulated by an electro-magnetic wave (light, for example) would give off a basic unit of light called the photon, which would have the same wave length as the stimulating wave. A number of subsequent experiments proved Einstein correct. But not until 1958 did Physicists Arthur Schawlow and Charles Townes describe a device that they thought would be able to stimulate molecules of gas confined in a cylinder until they gave off photons in an intense and powerful stream. Their device was a variation of Townes's earlier Nobel Prizewinning invention, the maser-an instrument that...
Just two years later, Physicist Maiman used the Townes-Schawlow theory and built the world's first working laser, a small, hand-held instrument that shot out bursts of brilliant red light. Instead of a gas, Maiman's laser used a synthetic ruby crystal grown in a bath of molten aluminum oxide. In pure form, the aluminum oxide crystal is colorless and transparent. But a pinch of chromium added to the bath as an impurity gives the resulting crystals their characteristic ruby-red hue and supplies the chromium atoms (one for every 5,000 aluminum atoms) that cause...
...conventional radar altimeter would have indicated only the slope of the stadium; the laser picked out each row of seats, the one-foot space between each row, and even the slight depression of the running track at ground level. In no more than 20 years, Physicist Schawlow predicts, the laser will be a common tool "in the office, in the factory, and in the home, where it could be used for peeling potatoes." Or, he says, as he casually lights a book of matches with a hand-held laser, "it might even be used as a pilot light for kitchen...
