FBH leads European diode-pumped laser efforts
EuPRAXIA selects second laser-driven accelerator site
The EuPRAXIA consortium has selected ELI Beamlines at ELI ERIC in the Czech Republic as the site for its laser-driven second plasma-accelerator pillar. This decision marks a major milestone in the consortium’s journey to pioneer compact, high-performance electron accelerators using laser- and beam-driven plasma wakefield acceleration technology. FBH plays a key role by contributing its expertise in diode laser pump technology.
EuPRAXIA aims to establish a pan-European research infrastructure that will lead to breakthroughs in accelerator science and drive innovations across scientific and industrial fields. Recognized in the 2021 Roadmap of the European Strategy Forum on Research Infrastructures (ESFRI), the initiative unites leading institutions across Europe to develop cutting-edge accelerator capabilities. The accelerator community’s efforts are further supported by the recently started EU-funded PACRI project, that pursues technology development towards next-generation plasma acceleration systems.
FBH and EuPRAXIA: strengthening collaboration in laser accelerator development
A key contributor to this project is FBH, a steadfast supporter of European efforts in advancing the high-energy-class laser field, especially recent efforts to pioneer laser-driven plasma acceleration facilities. A full member of the EuPRAXIA consortium – serving on both its steering committee and collaboration board – FBH co-leads the efforts in Laser Technology and Liaison to Industry in close collaboration with CNR-INO in Pisa, Italy. Together, they are working to ensure the development of large-scale diode-pumped laser systems that will be central to the project’s success.
“We are very excited about the formal selection of the second EuPRAXIA site at ELI ERIC,” says Dr. Paul Crump, project lead at the FBH and head of FBH’s High-Power Diode Lasers Lab. “Diode laser pumps are a critical technology for all high-energy-class laser systems, from the advanced accelerators developed by EuPRAXIA through to studies in fusion, as they are both essential system components and a significant cost factor. Our work drives the innovation needed to enable the industries of the future – for example, addressing future energy challenges by securing sustainable energy supplies through research into inertial fusion energy. We look forward to working closely with our partners to advance the field.”
FBH and PACRI: advancing laser plasma accelerator system efficiency
In parallel to its contributions to EuPRAXIA, FBH also plays a key role in the newly launched PACRI project (Plasma Accelerator systems for Compact Research Infrastructures). This EU-funded initiative focuses on advancing high-power, high-repetition-rate laser technology for next-generation plasma accelerators. Within PACRI, FBH leads the development of high-performance diode laser pumps – critical components that determine the efficiency, cost, and performance of large-scale laser systems. By working closely with industrial partners, FBH ensures that cutting-edge diode laser technology will be available for future accelerator infrastructures, including the second EuPRAXIA site at ELI ERIC in the Czech Republic.
Both EUPRAXIA and PACRI are funded by the European Union.
