Frequency-Stable Laser System for Use in Space

Scientists from the Humboldt-Universität zu Berlin (HU Berlin) and Ferdinand-Braun-Institut (FBH), also in Berlin, Germany, have developed a frequency-stable laser system for use in space. In the JOKARUS experiment (German acronym for iodine comb resonator under weightlessness), an active optical frequency reference based on molecular iodine was qualified for the first time in space.
