Referent: Prof. Dr. Karl MaierTag der Promotion: 23.07.2009AbstractLaser cooled atomic gases and atomic beams are widely studied samples in experimentalresearch in atomic and optical physics. For the application of ultra cold gases as modelsystemsfore.g. quantummanyparticlesystems, theatomicspeciesisnotveryimportant.Thus this field is dominated by alkaline, earthalkaline elements which are easily accessiblewithconventionallasersourcesandhaveconvenientclosedcoolingtransition. Ontheotherhand,lasercooledatomsmayalsobeinterestingfortechnologicalapplications,forinstancefor the creation of novel materials by atomic nanofabrication (ANF). There it will beimportanttousetechnologicallyrelevantmaterials. Asanexample, usinggroupIIIatomsoftheperiodicaltableinANFmayopenaroutetogeneratefully3Dstructuredcompositematerials. The minimal requirement in such an ANF experiment is the collimation of anatomic beam which is accessible by one dimensional laser cooling.
