Power of New Laser Beam like Focusing All the Sun's Light toward Earth into One Grain of Sand Teresa Neumann (February 20, 2008) Scientists now hope to explore the theory that extreme focused lasers can "generate matter by merely focusing light into empty space" Hercules laser(University of Michigan)—Science Daily reports that if you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam made in a University of Michigan laboratory. (Photo Credit: Anatoly Maksimchuk/EECS) "That's the instantaneous intensity we can produce," said professor Karl Krushelnick. "I don't know of another place in the universe that would have this intensity of light. We believe this is a record." Notes the report: "The record-setting beam measures 20 billion trillion watts per square centimeter. It contains 300 terawatts of power. That's 300 times the capacity of the entire U.S. electricity grid. The laser beam's power is concentrated to a 1.3-micron speck about 100th the diameter of a human hair. A human hair is about 100 microns wide." As an aid in helping researchers explore new frontiers in science, the report states that at even more extreme intensities, laser beams could potentially "boil the vacuum," which scientists theorize would generate matter by merely focusing light into empty space.
