Laser Spectroscopy and Laser Cooling of Indium — •Bernhard Klöter, Ruby dela Torre, Jiayu Wang, Dietmar Haubrich, Ulrich Rasbach, and Dieter Meschede — Institut für Angewandte Physik der Universität Bonn

Indium is an interesting candidate for Atomic Nanofabrication (ANF) because it can directly be deposited onto a substrate. The high deposition rates needed for ANF can only be achieved with a laser cooled thermal Indium atomic beam, which had not been established before.

We first systematically investigated laser frequency stabilization schemes for all five frequencies involved in the cooling process.

The poster will present our results on saturation and polarization spectroscopy of Indium in an all sapphire cell at 410 nm and/or 451 nm, the laser frequency locking schemes and the different laser cooling methods.
