[0:19] When Al Giddings first began diving more
[0:21] than 30 years ago, there were no
[0:23] underwater housings available to protect
[0:25] the cameras of daredevil undersea
[0:27] photographers like himself.
[0:32] What you're seeing is the tremendous
[0:34] power of a nuclear electric plant
[0:36] concentrated into a laser beam.
[0:40] The UCLA School of Dentistry is using
[0:43] facial prosthetics in a unique marriage
[0:45] of art, science, and medicine. The same
[0:47] technology used to replace a missing
[0:49] tooth is making people whole again.
[0:54] Hello, I'm Richard Hart. The world's
[0:57] biggest laser, in the blink of an eye,
[0:59] generates as much power as all of the
[1:01] United States of America. It was built
[1:03] for military research, and as the
[1:05] science fiction movie cliche goes, it
[1:07] can be used for good or evil. The choice
[1:09] is ours. Well, the people who make
[1:11] computer chips have come up with one
[1:13] good idea.
[1:24] What you're seeing is the tremendous
[1:26] power of a nuclear electric plant
[1:28] concentrated into a laser beam.
[1:34] In a joint project between the Lawrence
[1:36] Livermore National Lab and Hampshire
[1:38] Instruments, laser technology, initially
[1:41] developed to shoot down high-flying
[1:43] missiles for the Star Wars program, is
[1:45] now being used to manufacture computer
[1:47] chips.
[1:51] >> This is a
[1:53] 25 joule per pulse flash lamp pump glass
[1:57] regenerative amplifier system. It
[2:00] delivers 25 joules at up to 3 hertz and
[2:03] a 10 nanosecond pulse.
[2:08] >> What that does is when the beam strikes
[2:10] say iron or copper, huge amounts of
[2:13] invisible x-rays are released. But that
[2:15] takes awesome power, power measured in
[2:18] gigawatts.
[2:19] >> 2 gigawatts is
