Neuer Super Laser: Bedeutung für Forschung und Energie?
Zur Zeit macht eine Meldung aus Kalifornien die Runde:
SAN FRANCISCO (AFP) – A US weapons lab on Friday pulled back the curtain on a super laser with the power to burn as hot as a star.
The National Ignition Facility's main purpose is to serve as a tool for gauging the reliability and safety of the US nuclear weapons arsenal but scientists say it could deliver breakthroughs in safe fusion power.
"We have invented the world's largest laser system," actor-turned-governor Arnold Schwarzenegger said during a dedication ceremony attended by thousands including state and national officials.
"We can create the stars right here on earth. And I can see already my friends in Hollywood being very upset that their stuff that they show on the big screen is obsolete. We have the real stuff right here."
NIF is touted as the world's highest-energy laser system. It is located inside the Lawrence Livermore National Laboratory about an hour's drive from San Francisco.
Equipment connected to a house-sized sphere can focus 192 laser beams on a small point, generating temperatures and pressures that exist at cores of stars or giant planets.
NIF will be able to create conditions and conduct experiments never before possible on Earth, according to the laboratory.
A fusion reaction triggered by the super laser hitting hydrogen atoms will produce more energy than was required to prompt "ignition," according to NIF director Edward Moses.
Ich hab mich immer schon gefragt wie man auf der Erde Plasma für einen Fusionsprozess herstellen will. Ich hätte allerdings nicht gedacht das ein Laser dafür jemals ausreichen könnte.
