We show that micro-machined non-evaporable getter pumps (NEGs) can extend thetime over which laser cooled atoms canbe produced in a magneto-optical trap(MOT), in the absence of other vacuum pumping mechanisms. In a first study,weincorporate a silicon-glass microfabricated ultra-high vacuum (UHV) cell withsilicon etched NEG cavities and alumino-silicateglass (ASG) windows anddemonstrate the observation of a repeatedly-loading MOT over a 10 minute periodwith a single laser-activated NEG. In a second study, the capacity of passivepumping with laser activated NEG materials is further investigated inaborosilicate glass-blown cuvette cell containing five NEG tablets. In thiscell, the MOT remained visible for over 4 days withoutany external activepumping system. This MOT observation time exceeds the one obtained in theno-NEG scenario by almostfive orders of magnitude. The cell scalability andpotential vacuum longevity made possible with NEG materials may enable inthefuture the development of miniaturized cold-atom instruments.
