Title: Frequency stabilization of diode lasers and possible applications for ultracoldatoms experiments
Speaker: M.Sc. Chi Zhang, University of Innsbruck, Austria
In this talk, first, two possible experimental schemes for ultracold fermionic atoms inside cavities will be presented. The first one is to measure the antiferromagnetism correlations in the two-dimensional Hubbard model; via the cavity-induced Bragg scattering of an off-resonant laser, which is amplified significantly by the cavity. The other scheme aims for the generation of a disordered optical lattice potential with cavities. Next I will talk about the technique part, which describes the frequency stabilization of external-cavity diode lasers with a high-finesse optical cavity by the Pound Drever Hall technique, as well as phase lock of optical fibers.
Coffee and cake will be served from 12:05
