Report: Compact, Precise Beam Could Aid in Nuclear Security

A Berkeley Lab-led report highlights a new, compact technique for producing beams with precisely controlled energy and direction that could “see” through thick steel and concrete to more easily detect and identify concealed or smuggled nuclear materials for national security and other applications.

R&D Effort Produces Magnetic Devices to Enable More Powerful X-ray Lasers

Teams of researchers working in a multi-lab collaboration have designed, built, and tested two magnetic devices called superconducting undulators. The effort could lead to a next generation of more powerful, versatile, compact, and durable X-ray lasers.

Special Delivery: First Shipment of Magnetic Devices for Next-Gen X-Ray Laser

The first shipment of powerful magnetic devices for a next-generation laser project arrived at their destination on Wednesday after a nearly 3,000-mile journey. Berkeley Lab is overseeing the development and delivery of these devices, called undulator segments.

Laser R&D Focuses on Next-Gen Particle Collider

A set of new laser systems and proposed upgrades at Berkeley Lab’s BELLA Center will propel long-term plans for a more compact and affordable ultrahigh-energy particle collider.

Seeing Atoms and Molecules in Action with an Electron ‘Eye’

A unique rapid-fire electron source—originally built as a prototype for driving next-generation X-ray lasers—will help scientists at Berkeley Lab study ultrafast chemical processes and changes in materials at the atomic scale.

Construction Begins on Major Upgrade to World’s Brightest X-ray Laser

Berkeley Lab scientists are developing key components for LCLS-II, a major X-ray laser upgrade and expansion project that will enable new atomic-scale explorations with up to 1 million ultrabright X-ray pulses per second.

Berkeley Lab Working on Key Components for LCLS-II X-ray Lasers

  X-ray free-electron lasers, first realized a decade ago, produce the brightest X-rays on the planet, and scientists tap into these unique X-rays to explore matter at the atomic scale and observe processes that occur in just quadrillionths of a second. As the name suggests, an X-ray free-electron laser requires electrons—lots of them, and in

‘Lasers Rewired’: Scientists Find a New Way to Make Nanowire Lasers

Scientists at Berkeley Lab and UC Berkeley have found a simple new way to produce nanoscale wires that can serve as bright, stable and tunable lasers—an advance toward using light to transmit data.

Coupling 2 ‘Tabletop’ Laser-Plasma Accelerators, a Decisive First Step Toward Tomorrow’s Ultrapowerful Compact Machines

Scientists at Berkeley Lab’s BELLA Center demonstrated that a laser pulse can accelerate an electron beam and couple it to a second laser plasma accelerator, where another laser pulse accelerates the beam to higher energy—a fundamental breakthrough in advanced accelerator science.

Exciting Breakthrough in 2D Lasers

An important step towards next-generation ultra-compact photonic and optoelectronic devices has been taken with the realization of a two-dimensional excitonic laser. Berkeley Lab researchers have embedded a monolayer of tungsten disulfide into a microdisk resonator to achieve bright excitonic lasing at visible light wavelengths.
