National Ignition Facility sets new laser energy record
Lawrence Livermore National Laboratory’s National Ignition Facility laser system has set a new record, firing 2.15 megajoules (MJ) of energy to its target chamber—a 15 percent improvement over NIF’s design specification of 1.8 MJ, and more than 10 percent higher than the previous 1.9 MJ energy record set in March 2012.

The Twinkle in Mother Earth’s Eye: Laser Blasts Produce Promising Fusion Advances
What if you could have a miniature star powering your house, your computer, and your car? How cool would that be! Stars produce a lot of energy, and they get that energy through a process called fusion. Thanks to recent research at the National Ignition Facility, we’re now one step closer to using fusion as a power source—unlocking a virtually infinite supply of clean energy. (physics central)

Giant lasers pass new milestone towards fusion energy
Physicists working at the National Ignition Facility in the US say they have passed another important milestone in their quest for nuclear fusion energy. They have shown that the fusion energy generated by the laser implosion of a deuterium-tritium fuel capsule is twice that of the kinetic energy of the implosion. By further trebling the fusion energy, they say they will be close to the long-sought goal of an overall net energy gain. (Physics World)

NIF achieves new fusion output milestone
Researchers at the National Ignition Facility have taken another step toward their long-overdue goal of using lasers to attain a self-sustaining nuclear fusion reaction. On 14 June in Physical Review Letters, researchers described experiments that doubled previous records both for neutron yield (now at 1.9 x 1016) and fusion energy output (now at 54 kilojoules) generated from capsules containing cryogenic deuterium–tritium fusion fuel.

7 Giant Machines That Changed the World—And 1 That Might
NIF’s lasers are used to create conditions not unlike those within the cores of stars and giant planets, which helps scientists to gain understanding about these areas of the universe. The NIF is also being used to pursue the goal of nuclear fusion. If we can crack the code for this reaction that powers stars, we’ll achieve unlimited clean energy for our planet. (Mentalfloss.com)

Scientists May Use Lasers to Gauge if "Super-Earths" are Fit for Life
So-called “super-Earths” are the exoplanet du jour, probably because they remind us so much of home. These worlds—which have a mass higher than Earth’s but less than Neptune’s—are thought to be fairly common outside our solar system. Now, scientists using lasers to test iron samples in an experiment that could set up how we one day will gauge whether super-Earths are fit for life. (inverse.com)
