LLNL supports successful demonstration of a new space inspection capability

Over the past decade, global space launch cadences have grown dramatically, frequently placing multiple payloads into orbit on a single booster. Robust Space Domain Awareness (SDA) and precise characterization of resident space objects are vital to safeguarding the orbital environment. To confront this emerging national security risk, a team of scientists at Lawrence…

3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times

At the bottom of the ocean, optical fibers transmit telecommunications and internet data across the world. Waveguides make that feat possible by channeling and amplifying the light — and therefore the data within — over enormous distances. And the technology goes beyond undersea cables. Waveguiding optics are among the most important advances in photonics since the…

LLNL scientists and engineers learned to turn events too fast, too hot and too dense to touch into knowledge.

The Big Ideas Lab takes measure of NIF diagnostics

How do you measure what can’t be seen? In the medical field, this is routine. Thermometers check temperatures and X-rays can show broken bones. But what if you are trying to measure something hotter than the center of the sun that vanishes in 100 trillionths of a second? What if it’s an experiment on Lawrence Livermore National Laboratory’s National Ignition Facility (NIF)…

Measuring iron in motion at earth-core conditions

It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from the Earth’s surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several universities used the National Ignition Facility (NIF) to recreate those extreme temperature and pressure conditions of the Earth’s inner core…

Researchers create first-of-a-kind laser spring with LLNL’s highest-precision optics to date

When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated a rotating, spring-shaped laser pulse, opening up new possibilities for fusion energy, particle acceleration, astrophysics and beyond. In new…

Laser experiments push helium to record shock pressures

Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth’s atmosphere. At those conditions, helium may separate from hydrogen and influence a planet’s internal heat flow, structure and magnetic field. Understanding these processes and how these materials behave under extreme conditions is essential to…

In an inertial confinement experiment on the National Ignition Facility, the lasers converge at tiny entrance holes at the top and bottom of the hohlraum. The intersection of the lasers enables crossed-beam energy transfer, an important factor in maintaining symmetry of implosions.

Research sheds new light on laser polarization effects in NIF experiments

Experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the top or bottom of a 2-centimeter gold canister known as a hohlraum. As they enter, the beams intersect in plasma and transfer power, a process known as…

Flash X-Ray

Meet the machines that matter: the Flash X-Ray

At your dentist's office, an X-ray machine fires a brief pulse of radiation, enough to find a cavity. Now imagine scaling that concept up by billions, producing a flash powerful enough to see through more than a foot of solid steel and capture a stop-motion image of an explosive experiment in progress. That's the Flash X-Ray machine, or FXR, at Lawrence Livermore National…

NASA's Roman telescope poised to transform hunt for elusive neutron stars

Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively invisible. A new study published in Astronomy and Astrophysics suggests NASA’s upcoming Nancy Grace Roman Space Telescope could spot them anyway. Using detailed simulations of…
