The JOKARUS project

In the JOKARUS project (german acronym: Jod Kamm Resonator unter Schwerelosigkeit) we miniaturize a Doppler-free MTS frequency reference where a micro-integrated ECDL laser is stabilized to hyperfine transitions in molecular iodine at 532 nm. We optimize this optical absolute frequency reference for autonomous operation onboard a TEXUS sounding rocket starting May 2018. The frequency of the iodine reference will be compared to an optical frequency comb flying as a seperate payload bulid by Menlo System.
