PETAL is made of 3 differents stages.
- The laser stage:
the first sub-assembly generates ultrashort pulses, which are then stretched from femtosecond to nanosecond duration to be amplified from 3nJ to 100mJ,
an amplifier section based on LIL arrangement will deliver 6kJ of infrared laser beam,
a vacuum compression chamber will deliver a Multi-Petawatt laser beam of picosecond or femtosecond pulses, with energies of several kilojoules,
several vacuum tubes will transport the laser beam to the experimental room.
- An independant system dedicated to beam characterization is implemented into the "Petawatt-SCF" room.
- The petawatt beam will be introduced, focalised and coupled with the LIL thanks to an opto-mechanics system.
