Abstract: |
The Extreme Light Infrastructure (ELI) Project was first proposed in 2005. During
the preparation phase the white books for the 3 pillars were established. Financed by the European union this 850 Millions Euros project is distributed over 3 countries: Czech Repulic, Hungaria and Romania. The ELI-NP (Nuclear Physic) part in Romania requires a Laser able to deliver 2x100TW at 10Hz, 2x1PW at 1 Hz and 2x10PW at 1shot per minute. This will make this laser the most powerful laser in the world. Thales was awarded the development and construction of this laser in July 2013. We are now in the installation phase of this project. 100TW and 1PW outputs have already been demonstrated on site and the 10PW line is under assembly. Such a laser involves numerous breakthroughs in order to achieve these extreme parameters. The solution taken is based on hybrid approach between OPCPA (Optical Parametric Chirp Pulse Amplification) and Ti:Sapphire amplifier. Procurement of optics was a challenge (meter size gratings, 200mm diameter Ti:Sapphire Crystals, ...) but the technical challenges were also high. The pulse requires a excellent contrast, as well as an excellent focusability. We will detail in this presentation the solution we choose in order to build such a laser and the results we obtained. |
