"The new amplifier of the HERCULES laser fires. The laser is now capable of producing a beam so intense scientists believe it sets a world record."
"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."
