| Resumo | |
We report on our progress in the construction of a continuous matter wave interferometer for inertial sensing via the non-destructive observation of Bloch oscillations. At the present stage of the experiment, around 10(5) strontium-88 atoms are cooled down to below 1 mu K. Pumped by lasers red-tuned with respect to the 7.6 kHz broad intercombination transition of strontium, the two counterpropagating modes of the ring cavity form a one-dimensional optical lattice in which the atoms, accelerated by gravity, will perform Bloch oscillations. The atomic motion can be monitored in real time via its impact on the counterpropagating light fields. We present the actual state of the experiment and characterize the laser spectrometer developed to drive the atom-cavity interaction. (AU) | |
