Producer's Notes - Super Laser at the National Ignition Facility

Inside the National Ignition Facility. Lawrence Livermore National Lab is building the world's largest laser. Actually, the National Ignition Facility won't have only one laser beam. It will use 192 world-class lasers, all firing simultaneously. In a few billionths of a second about 500 trillion watts, which is nearly 1000 times the power generated in the entire US at any moment, will hit a target the size of a dime. The hope is that this will create enough heat and pressure to mimic the core of the sun and achieve a fusion ignition.

So in a nutshell, what is fusion? And how do lasers work? Why are you asking me? I was the kid who always struggled with math and would get hives on the eve of a high school science test.

Luckily, there are some darn good teachers out there and we were fortunate enough to feature one of them in our story. Richard Muller is a professor of physics at the University of California and has also become something of a web phenomenon. Thousands of "students" all over the world have viewed his lecture series titled "Physics for Future Presidents" on YouTube and Cal's own website.

Muller designed this class to "stress conceptual understanding rather than math, with applications to current events." As he told us, "imagine looking out on your classroom and picturing out there is the future president of the United States. What do you want that person to know?" What comes out is an explanation of the physics of energy, nuclear weapons, radioactivity, relativity and the universe– all explained in a way that the physics-challenged, like myself or maybe a future president, can understand.

Super Laser

It's one of the most expensive high-tech projects the United States has ever attempted, and some say it will never work. QUEST visits the National Ignition Facility in Livermore, where scientists will soon aim the world's largest laser at a target the size of a pencil eraser. The goal? Nuclear fusion — and, they say, the answer to the world's clean energy needs.
