Bloch oscillations in an optical lattice generated by a laser source based on a fiber amplifier: decoherence effects due to amplified spontaneous emission

M. Andia, Étienne Wodey, F. Biraben +2 more

We have developed a laser source generated by frequency doubling of a seed laser at 1560 nm using a periodically poled lithium niobate crystal. The seed laser passes through a 30 W fiber amplifier. The laser source at 780 nm is used to perform Bloch oscillations of ultra-cold atoms in an optical lattice. In this paper we investigate the decoherence effects induced by the amplified spontaneous emission (ASE) in the gain medium. We show that the ASE drastically reduces the efficiency of Bloch oscillations. We totally filter out the ASE around the D2 line using a heated rubidium vapor cell. We precisely determine the power spectral density of the ASE by measuring the fraction of atoms transferred from the hyperfine level F=1 to F=2, when the laser is switched on.

Preservation of atomic coherence in double-well optical lattice in presence of decoherence

Shubhrangshu Dasgupta

We present a quantum interference approach to preserve coherence in the external states of an atom trapped in an optical lattice. We show that this is possible by suitably choosing the initial state of the atom. We demonstrate this in context of decoherence due to spontaneous emission in an one-dimensional optical double-well lattice.
