Two-micron fill tubes fill two needs
Lawrence Livermore National Laboratory’s National Ignition Facility and General Atomics engineers have created an inertial confinement fusion (ICF) fuel capsule with a two-micron-diameter fill tube—and along the way, found a solution to a “Bay Bridge”-like dilemma that could have dramatically slowed the process of fabricating NIF capsules.

This Is Why the 2018 Nobel Prize in Physics, for Lasers, Is So Important
At first glance, a Nobel Prize for groundbreaking inventions in the field of laser physics might not seem to be such a big deal, given how commonplace lasers are. But if we look closer, you’ll understand why it’s not only Nobel-worthy, but why it’s so meaningful for the human enterprise of science. (Forbes)

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)

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.

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)
