The ELI-NP HPLS is the latest generation of Ti:Sa based lasers, involving two main laser beams of 10 PW peak power each,
at a repetition rate of 1 pulse per minute, seeded by a common 10mJ, 1013:1 temporal
contrast OPCPA based Front End. HPLS delivers also higher repetition rate laser pulses
with lower peak power, two 1PW outputs at 1 Hz and two 100TW outputs at 10Hz.
The entire laser system was completely commissioned at the end of 2019 after a first demonstration of its 10 PW pulse power capabilities in March, the same year.
The ELI-NP HPLS is the laser with the highest available peak power in the world to this date.

The Variable Energy Gamma (VEGA) System is a dedicated equipment for delivering gamma-ray
beams to users. Its delivery, installation and acceptance are scheduled to be completed
in early 2023.
The system will deliver gamma-rays with energy in a range relevant for nuclear physics and astrophysics studies, applied research in materials science, management of nuclear materials, and life sciences.
The VEGA System will be the most advanced gamma-ray source in the world compared with the current state-of-the-art.
