Abstract

Wavefront aberrations are today the main contribution in the inaccuracy budget of best cold atom interferometers [1, 2], based on laser beam splitters, and constitute an important limit for their long-term stability [1]. They prevent from exploiting the full potential of these atom interferometers. In this work, we report on the active control of laser wavefronts for atom interferometry and demonstrate in a proof-of-principle experiment the compensation of their aberrations using, for the first time, a deformable mirror in a cold atom inertial sensor.
