Laser R&D projects


XCAN


Laser systems based on solid amplifying media are reaching their physical limits in terms of aperture and extractable energy, limits which will not be overstepped without innovation in terms of material engineering and/or laser architectures.

The X-CAN project (École polytechnique & Thales) has been launched the 21st of April, 2015 to demonstrate coherent combination in the fs regime of about sixty amplifiers (microstructured optical fibers) at the 500W average power level.  The prototype will be hosted by the LULI laboratory to which is administratively attached the project manager: Jean-Christophe Chanteloup.

LUCIA


The objective of the LUCIA (Laser Ultra-Court Intense et Applications) project was to set up a high average power, high efficiency laser system based on a diode-pumped solid-state amplifier delivering more than 10 Joules in the nanosecond regime at a repetition rate higher than 1 Hz.

The project, led by J.-C. Chanteloup, was launched thanks to the 2000 - 2007 State-IdF CPER. It was regularly funded y the Direction Générale de l'Armement (DGA) and, depending from the years, by the European Commission, especially in the framework of the LASERLAB-EUROPE Joint Research Activities and of the workpackage #14 of the HiPER project. In 2016, it was integrated in the CELIA LEAP (Lasers énergétiques en Aquitaine pour les plasmas à haute puissance moyenne) project.

Apart from the laser chain design itself, various R&D activities were conducted on:

novel amplifying media (ceramics, gradually doped crystals, etc),

thermal management (minimization of the undesirable thermal effects: thermal lens, depolarization, etc)

ASE management.
