...apparatus is called a femtosecond laser because it emits pulses of light in extremely short bursts—the equivalent of a millionth of a billionth of a second...
...FEMTOSECOND LASERS. Like strobes flickering across a submicroscopic dance floor, these devices can freeze the gyrations of atoms and molecules with flashes of light. The lasers are being used to study everything from how sodium joins with other atoms to form salts to how plants convert sunlight into energy through the process of photosynthesis. Physicists from California's Lawrence Berkeley Laboratory reported that they used such a laser to take a "snapshot" of the chemical reaction that is the first step in visual perception. This reaction, triggered when light hits the retina of the eye, had never before been directly...
...positioning system enough to land airplanes in pea-soup fog." Even now it is not difficult to imagine that STMs might be employed by the semiconductor industry to produce minuscule electronic devices, that optical tweezers might be used by surgeons to correct defects in a single cell or that femtosecond lasers might eventually be harnessed to control, as well as monitor, chemical reactions. Speculates University of Chicago chemical physicist Steven Sibener: "In the future, combinations of these magic wands may become much more powerful than using them...
