A laser cooled Indium atomic beam for atomic nanofabrication — •Bernhard Klöter, Dietmar Haubrich, and Dieter Meschede — Institut für Angewandte Physik, Wegelerstr. 8, 53115 Bonn

Laser cooled atomic beams are the method of choice for Atomic Nanofabrication (ANF) where high deposition rates are needed. We have realized 1D transverse cooling of a neutral Indium atomic beam with a Λ-type cooling scheme which involves five laser wavelengths at 410 nm and 451 nm. We present our systematic studies of these schemes concerning the role of external magnetic fields, interaction length and laser parameters such as polarisation and intensity.
