Description
Magneto-optical traps (MOTs) are a central tool for producing and confining ultracold atomic gases. Most experiments rely on type-I MOTs, which exploit closed cycling transitions to provide strong radiation-pressure forces and efficient cooling. More recently, however, type-II MOTs, in which closed cycling transitions are absent, have been used in several laser cooling experiments.
Experimental and theoretical studies have demonstrated that atom capture in a type II MOT can significantly suppress light-assisted collisions and re-absorption-induced heating. These effects reduce density-limiting loss mechanisms and lead to colder, higher-density samples that are well suited for subsequent loading into shallow optical traps.
In this work, we present results on the efficient operation of a type-II MOT for Cs. We also report a characterization of a type-I MOT and ongoing progress toward the realization of a type-II MOT for lithium.
