The combination of our narrow linewidth cavity (451 kHz) and strongly confining dipole traps (600 kHz to 2 MHz trapping frequencies) is an ideal setup for realizing sideband-resolved cavity-cooling close to quantum-degeneracy : the atoms scatter photons from a pump beam into the cavity mode at a detuning corresponding to the trapping frequencies and release a quantum of kinetic energy in the process.
Currently, Li6 atoms can be trapped and imaged inside the intra-cavity dipole trap at 1342nm. Dispersive interaction of the atomic cloud with the cavity mode has been verified and we have the first evidence of scattering from a side pump into the cavity mode. I will summarize the important ideas and technical developments behind the design,
present the current status of our experiment and the next steps towards sideband-resolved cavity cooling.
