Abstract

A method for combining laser cooling on two transitions of metastable helium to obtain a high phase-space density was described. A sequence of a large 1083 nm magneto-optical trap (MOT) and a compressed 389 nm MOT was runned for a density increase of more than one order of magnitude. The results show that the phase-space density increases. The achieved low temperature makes the scheme fully exchangeable with 1083 nm molasses.
