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.
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.
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.
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
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.
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.
Using one of the most powerful lasers in the world, Berkeley Lab researchers have accelerated subatomic particles to the highest energies ever recorded. They used an emerging class of compact particle accelerator that physicists believe can shrink traditional, miles-long accelerators to machines that can fit on a table.
Berkeley Lab researchers report a significant breakthrough in laser technology with the development of a unique microring laser cavity that can produce single-mode lasing on demand. This advance holds ramifications for a wide range of optoelectronic applications including metrology and interferometry, data storage and communications, and high-resolution spectroscopy.
