The L3-HAPLS modernized petawatt laser complement was commissioned final week during the ELI Beamlines Research Center (link is external)in Dolní Břežany, Czech Republic. L3-HAPLS — a world’s many modernized and top normal power, diode-pumped petawatt laser complement — was designed, grown and fabricated in usually 3 years by Lawrence Livermore National Laboratory’s (LLNL) NIF and Photon Science (NIFPS) Directorate and delivered to ELI Beamlines in Jun 2017.
Since a finish of September, an integrated group of systematic and technical staff from LLNL and ELI Beamlines has worked intensively on a designation of a laser hardware. All laser support systems, such as opening and cooling, were connected to a building, signaling willingness to spin a laser behind on in a new home.
L3-HAPLS consists of a categorical petawatt beamline, energized by diode-pumped “pump” lasers. The complement was constructed, fabricated and ramped to an surrogate opening miracle that demonstrated a capability and noted a miracle for shipping and integrating with a facility. Staff from ELI was extensively lerned on a laser’s public and operation while during Livermore to safeguard success in transferring a HAPLS record to a ELI user facility.
In early 2018, a L3-HAPLS system’s high appetite siphon laser will be gradually brought adult to prior performance, followed by ramping a petawatt beamline initial in appetite and afterwards in normal power.
“Over a march of some-more than 4 decades, LLNL has built an general repute for building some of a world’s some-more absolute and formidable lasers,” LLNL Director Bill Goldstein said. “The successful smoothness and designation of L3-HAPLS represents a new era of high-energy, high-peak-power laser appetite systems. This collaboration, and others like it, yield LLNL with a event to lift on a tradition of redefining a bounds of scholarship and technology.”
LLNL’s decades of cutting-edge laser investigate and growth led to a pivotal advancements that heed L3-HAPLS from other petawatt lasers: a ability to strech petawatt appetite levels while progressing an rare beat rate; growth of a world’s top rise appetite diode arrays, driven by a Livermore-developed pulsed appetite system; a siphon laser generating adult to 200 joules during a 10 Hz exercise rate; a gas-cooled short-pulse titanium-doped turquoise amplifier; a worldly control complement with a high turn of automation including auto-alignment capability, quick laser startup, opening tracking and appurtenance safety; a dual chirped-pulse-amplification high-contrast short-pulse front end; and a gigashot laser siphon source for pumping a short-pulse preamplifiers.
Despite a complexity, L3-HAPLS was designed for a user facility. The concentration is on a focus or experiment, and a laser contingency run reliably, dynamically and with minimal user involvement during record performance. This ability already has been demonstrated during a exam runs during LLNL.
“L3-HAPLS is a quantum burst in technology. Not usually did it concede LLNL to exam and allege new laser concepts critical for a goal as a inhabitant lab, it also is a initial high rise appetite laser that can broach petawatt pulses during normal appetite – some-more than 1 megajoule/hour – entering a industrial focus space,” pronounced Constantin Haefner, LLNL’s module executive for Advanced Photon Technologies (APT) in NIFPS. “Innovations driven by L3-HAPLS, such as a semiconductor laser diode pumps or mid-scale Green DPSSL technology, already have reached a marketplace — an critical sign that investment in laser record spurs enrichment in areas good over science.”
When commissioning during ELI Beamlines is finish subsequent year, L3-HAPLS will have a far-reaching operation of uses, ancillary both simple and practical research. By focusing petawatt rise appetite pulses during high power on a target, L3-HAPLS will beget delegate sources such as electromagnetic deviation or accelerate charged particles, enabling forlorn entrance to a accumulation of investigate areas, including time-resolved electron and X-ray radiography, laboratory astrophysics and other simple scholarship and medical applications for cancer treatments, in further to industrial applications such as nondestructive analysis of materials and laser fusion.
