Call for proposals
Laser4EU offers unique research opportunities to users from both academia and industry from all over Europe and to a limited extent to participants from outside Europe. Access is provided
• to world-class laser research facilities,
• to a large variety of inter-disciplinary research,
• free of charge, including travel and accommodation.
Access is provided on the basis of scientific excellence of the proposal, reviewed by an external and independent Selection Panel. Priority is given to new users. A typical access project has a duration of 2 to 4 weeks. Proposals for longer visits are highly exceptional.
Details about the application procedure can be found here. Applicants are strongly encouraged to contact the individual facilities directly for additional information and assistance in preparing their proposals.
We particularly welcome early-career researchers and those who have not previously used lasers in their work. Lasers4EU is committed to promoting gender equality in scientific research and especially encourages applications from women.
Rolling Call for Access Proposals
Lasers4EU operates a rolling call, meaning that access proposals may be submitted at any time by any eligible researcher or research team. This flexible approach is designed to accommodate a range of research schedules and encourage broad participation.
However, please note that specific submission deadlines apply for certain facilities, including LULI, CLF, GSI, FELIX, FERMI, and CLPU. For these infrastructures, proposals must be submitted in accordance with the relevant open call deadlines. Details of these calls can be found below.
Specific Calls

Twice a year, researchers can apply for either magnet time, FEL beam time or a combination thereof. The deadlines for submitting a proposal are 15 May and 15 November. Find out more here.
