ELI Delivery Consortium

ELI Beamlines is part of the Extreme Light Infrastructure (ELI) project (www.eli-laser.eu), a new Research Infrastructure of pan-European interest and part of the European Strategy Forum on Research (ESFRI) Roadmap. ELI will be a multi-sited Research Infrastructure with complementary facilities located in the Czech Republic, Hungary, and Romania for the investigation of light-matter interactions at the highest intensities and shortest time scales.

The laser intensity will be more than six orders of magnitude higher than today’s state of the art. ELI Beamlines is located in Dolní Břežany on the outskirts of Prague, the capital of the Czech Republic. ELI Beamlines is managed by the Institute of Physics of the Czech Academy of Sciences.


In response to the objectives of the of ELI Beamlines facility, the laser systems must provide the following main features:

  • For fundamental and applied research projects: Laser pulses with high repetition rates delivering multi-10 TW (terawatt) to PW peak power with high user versatility.

  • For fundamental science research projects: Ultra-high peak power of 10 PW (petawatt) providing focused intensities up to 1024 W/cm2 at increased shot rates.

Main Characteristics

ELI is a new type of large scale laser infrastructure specifically designed to produce the highest peak power and focused intensity, the first exawatt class laser, equivalent to 1000 times the National Ignition Facility (NIF) power. Some of ELI's main characteristics are:

1. ELI will be the world’s first international laser research infrastructure, pursuing unique science and research applications for international users.

2. ELI is the first ESFRI project to be fully implemented in the newer EU Member States.

3. ELI is pioneering a novel funding model combining the use of EU structural funds (ERDF) for the implementation, and member contributions to a yet to be established European Research Infrastructure Consortium ERIC for the operation.

ELI's Timeline

ELI Beamlines has been designed as the high-energy, high repetition-rate pillar of the Extreme Light Infrastructure (ELI). The top-level goal in implementing the project, as endorsed in the ELI White Book, is to establish a high-energy beam facility, responsible for development and use of ultra-short pulses of high-energy particles and radiation stemming from relativistic and ultrarelativistic interactions.

ELI Beamlines is intended to address one of the “grand challenges,” specifically in the generation of ultra-short pulses of energetic particles (>10 GeV) and radiation (up to few MeV) beams produced from compact laser plasma accelerators, and is expected to support the “Ultra-high field Science, i.e. access of the ultra-relativistic regime”. The laser resources that will be available at the ELI Beamlines facility have been suggested by a Technical Design Review.

The laser resources described there have been designed to address specific scientific challenges as identified by the international consortium within the ELI Preparatory Phase, namely in the fields of particle acceleration by lasers, generation of high-brightness XUV and X-ray pulses, and high-field physics. The ultrashort pulsed sources of energetic particles and radiation that are generated are designed to serve fundamental research and multidisciplinary applications.
