New Super Laser unveiled

Tim Sayell sends in this very interesting article from Yahoo News which reports that The National Ignition Facility has disclosed information describing a new "super laser". The new laser is capable of reaching temperatures and pressures equal to that said to exist in the cores of stars. This mean that for the first time in history, this was the first demonstration of fusion ignition in a laboratory setting.

What is really impressive is the physical makeup of the laser array. a house-sized sphere can focus 192 laser beams on a small point, generating temperatures and pressures that are capable of a fusion reaction triggered by the super laser hitting hydrogen atoms. There is ever indication that this reaction will produce more energy than was required to prompt "ignition," which had been the "holy grail" of fusion researchers for more than 50 years.
