Extreme Light Infrastructure
The Extreme Light Infrastructure (ELI) is a research organization with the world's largest collection of high power-lasers. ELI operates several high-power, high-repetition-rate laser systems which enable the research of physical, chemical, materials, and medical sciences.
ELI is part of the European Research Infrastructure Consortium (ERIC), where the official name and abbreviation came from: ELI ERIC. The organization consists of three complementary facilities, as well as collaborations with universities and research labs across the world. One of the facilities is ELI Beamlines, located outside of Prague in Dolní Břežany, Czech Republic; another facility, ELI ALPS (Attosecond Laser Pulse Source), is located in Szeged, Hungary; and the third facility is located in Măgurele, Romania (ELI Nuclear Physics, abbreviated as ELI NP).
From 2007 to 2010 ELI entered into a European-Commission-funded preparatory phase, comprising 40 laboratories from 13 countries. Gérard Mourou, the initiator of the ELI project, was the coordinator of the preparatory phase.
At the meeting of the Steering Committee in October 2009 in Prague, the ELI Preparatory Phase Consortium officially gave the mandate to the Czech Republic, Hungary and Romania to proceed towards the construction of ELI. On December 10, 2010, at the end of the preparatory phase, the project was fully handed over to the ELI Delivery Consortium, consisting of representatives from the three host countries. ERDF funding of the ELI-Beamlines facility in the Czech Republic was granted by the European Commission on April 20, 2011, followed by ELI-Nuclear Physics in Romania on September 18, 2012. Funding for the ELI-ALPS facility in Hungary was granted in early 2014.
The ELI Delivery Consortium International Association (ELI-DC) non-profit association was founded on April 11, 2013. On April 30, 2021, the European Commission granted ELI the legal status of an ERIC.
ELI Beamlines is located in Dolní Břežany near Prague, Czech Republic. ELI Beamlines operates high peak-power femtosecond laser systems with high-energy and high-repetition-rate capability, as well as secondary sources (X-rays and accelerated particles). The facility opened in 2015. User experiments started in 2018. There are four primary sources at ELI Beamlines, seven secondary sources and five scientific endstations and experimental platforms.
L1 ALLEGRA – TW laser, 100 millijoule, 1 kHz – status: in operation – The L1 ALLEGRA laser was developed in house by the ELI Beamlines laser team. The concept of the laser is based entirely on amplification of frequency chirped picosecond pulses in an optical parametric chirped pulse amplification (OPCPA) chain consisting of a total of seven amplifiers. The OPCPA amplifier stages are pumped by precisely synchronized picosecond pulses generated by state-of-the-art thin-disk-based Yb:YAG laser systems.
L2 DUHA – 100TW laser, 2 joule, 50 Hz – status: in operation – The L2 DUHA laser is designed to provide 100 TW-level pulses at a high repetition rate (50 Hz) at 820 nm, falling between L1-ALLEGRA and L3-HAPLS in terms of peak power. L2-DUHA is the newest of the ELI Beamlines laser systems and is currently in development with expected completion in the first half of 2024.
