Herein, we report the results of our laser cooling experiment in TianGong-2 space lab, which operated for 34 consecutive months in orbit. Over such an extended operation time, the quality of laser cooling did not experience any significant decline, while the properties of laser cooling in orbital microgravity were systematically studied. In particular, we demonstrate magneto-optical trapping and polarization-gradient cooling in orbit and carefully examine their performances. A comparison of the in-orbit and on-ground results indicates that a higher cooling efficiency exists in microgravity, including a smaller loss rate during the trapping and cooling process and lower ultimate temperature of laser-cooled atoms. Our progress has laid the technical foundations for future applications of cold atoms in space missions with operation times of the order of years.<\/jats:p>","DOI":"10.1093\/nsr\/nwac180","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T12:06:48Z","timestamp":1661774808000},"source":"Crossref","is-referenced-by-count":14,"title":["Characterization
