Active Control of Laser Wavefronts in Atom Interferometers

Optical aberrations in light-pulse atom interferometers are a major limitation in the accuracy and stability of these quantum sensors. In a proof-of-principle experiment, the authors use a deformable mirror to actively control the laser wave fronts in a cold-atom gravimeter, compensating for the distortions induced by optical elements. This fine control of wave fronts opens perspectives for atom interferometry, with applications in navigation, space physics, and high-precision metrology.
