The Laser Laboratory for Acceleration and Applications (L2A2) is a research infrastructure of the University of Santiago de Compostela equipped with an ultra-intense ultra-short laser system. The facility is being used by researchers from USC and external collaborators conducting research in the field of laser-plasma particle acceleration and femtosecond laser pulses applications.

The main facility in L2A2 is an ALPHA 10/XS laser system produced by THALES with two laser outputs. The pulses delivered by these two outputs are:

• Low energy line: pulses of 1 mJ with a 1 kHz rate, a duration between 35 and 100 fs and contrast ratio of 10⁶.
• High energy line: pulses of 1.4 J with a 10 Hz rate, a duration between 25 and 100 fs and contrast ratio of 10¹⁰

L2A2 is also equipped with a radioprotected area for laser-plasma acceleration experiments, in particular the LaserPET experiment, and a laboratory supporting these activities.
