Job Details

ELI-Beamlines is a research facility dedicated to using high intensity lasers to drive experiments for users and part of the larger ELI – ERIC research consortium. In order to provide the widest range of experimental opportunities in a single facility, ELI-Beamlines has 4 state-of-the-art high power lasers with output peak powers ranging from TW to 10 PW levels. The lasers are at varying stages of development with some nearing completion and others already running experimental campaigns for users. Several technologies are utilized in these lasers such as high power diode pumped solid state laser (DPSSL) technology, Ti:Sapphire amplification, optical parametric chirped pulse amplification (OPCPA), Nd:glass amplification, and fiber lasers/amplifiers. A brief summary of the beamlines is provided below:

L1-Allegra is a 1 kHz, 50 mJ laser based entirely on thin disk DPSSL pumped picosecond OPCPA. This laser is used regularly for user experiments and is currently being upgraded to have an auxiliary pulse train and a higher output energy of 100 mJ.

L2-DUHA is under development and is designed to be a 100 TW, 50 Hz laser for driving a laser wakefield accelerator. This laser based on high energy OPCPA pumped by a cryogenically cooled Yb:YAG multi-slab DPSSL.

L3-HAPLS is a 10 Hz, 1 PW laser which was developed by Lawrence Livermore National Laboratory. This laser is currently being used in user experiments and performance ramping of the laser to improve the output parameters has begun.

L4-Aton is a kJ-class laser with a design peak power value of 10 PW firing once every 5 minutes and based on amplification via OPCPA and Nd:glass. Commissioning is ongoing with a primary focus on compression of the high energy pulse to 10 PW peak power.

We are looking for:Laser scientist (125)


The successful candidate will contr  vibute to the development/upgrade of a laser as a member of the laser development team. This contribution can take many forms and will typically include some combination of practical laboratory work, numerical simulations of optical systems and physical processes, and design and construction of optical subsystems. The nature of the contribution would be determined in part by the interests of the applicant as well as the needs of the project. Possible areas of focus include, but are not limited to, the implementation of high energy OPCPA, compression of high peak power (100 TW to multi-PW) laser pulses, ultra-short pulse diagnostics and characterization, high energy/average power DPSSL development, precision synchronization of ultrashort pulse trains, and beam manipulation and imaging of large aperture lasers.


  • actively contribute to the development of the laser in the lab and assist younger scientists and students;
  • assist with the design of subsystems of the laser and be able to take the lead on certain aspects of the laser development;
  • perform calculations and develop models of optical systems, typical examples could be laser energetics, beam propagation, or nonlinear interactions of light pulses;
  • prepare manuscripts for publication in academic journals and present experimental results at scientific conferences.

We offer

  • the opportunity to participate in this unique scientific project;
  • competitive and motivating salary;
  • flexible working hours;
  • nice working environment;
  • career growth;
  • meal allowance, pension contribution and 6 sick days;
  • support of leisure time activities.

ELI Beamlines profile imageELI Beamlines is part of the European ELI laser centre, the world’s first international laser facility. ELI Beamlines is open to an international and interdisciplinary user community from academia and industry. Mandated by the international scientific laser community and implemented in the Czech Republic, Hungary and Romania, ELI drives international laser research and laser-based applications to new frontiers, and fulfils important missions for regional socio-economic development.

About us
The main mission of ELI Beamlines is to provide a user-oriented infrastructure for performing revolutionary scientific experiments across many different disciplines. It combines advanced synchronized ultra-intense short-pulse lasers with secondary sources of particles and X-rays.

The ELI Beamlines facility provides research opportunities at a number of world-class secondary sources, each one driven by ultra-intense lasers. These secondary sources, partially based on entirely new concepts, produce pulses of radiation and particles of the highest intensity and beam quality, including electromagnetic radiation over a broad spectral range and charged particles such as electrons, protons and ions. These will enable a wealth of novel applications.

The ERIC is a specific legal form designed to facilitate the establishment and operation of research infrastructures of European interest. ERICs are participated by States and international organizations as members. As a main statutory mission, ELI ERIC is responsible for making the ELI facilities available to the scientific community as a single international organization, with unified governance and management.

The Czech Republic hosts the ELI ERIC statutory seat in Dolní Brezany, in the South of Prague, at the ELI Beamlines facility. A second facility, ELI-ALPS, is hosted by Hungary in Szeged. The Czech Republic and Hungary are joined by Italy and Lithuania as founding members, while Germany and Bulgaria are founding observers. A third ELI facility is under construction in Romania in the field of nuclear photonics and is expected to complement the current ELI ERIC facilities in the future. More information can be found on the ELI ERIC websites.

Why work for us
ELI Beamlines brings together people from all over the world. If you want to participate in the largest laser research project in the world, apply through the offer of employment at We are interested in people of various professions and specializations. We can offer interesting and challenging work, dedicated training, plus the chance to work with smart people in a pleasant working environment.

The future is in laser technologies. Are you interested? Join us!
