The University of Michigan has developed a record-setting intense laser, HERCULES, that could help scientists develop better proton and electron beams for radiation treatment of cancer and explore new frontiers in science. This intensity is about two orders of magnitude higher than any other laser in the world can produce. The pulsed laser beam lasts just 30 femtoseconds. A femtosecond is a millionth of a billionth of a second.
 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. "That's the instantaneous intensity we can produce," said Karl Krushelnick, a physics and engineering professor. "I don't know of another place in the universe that would have this intensity of light. We believe this is a record."
