Automatization of a spaceborne iodine frequency reference based on a diode laser at 1064 nm — •Franz Gutsch1, Klaus Döringshoff1, Vladimir Schkolnik1,2, Markus Krutzik1, Achim Peters1,2, and The JOKARUS Team1,2,3,4,5,6 — 1Institut für Physik, Humboldt-Universität zu Berlin — 2FBH, Berlin — 3ZARM U Bremen — 4DLR Bremen — 5JGU Mainz — 6Menlo Systems GmbH
Spaceborne laser-based frequency references can deliver high accuracy and stability needed to further explore the foundational principles of General Relativity in future experiments, such as tests of the gravitational redshift or gravitational wave astronomy (e.g. eLISA).
We present a compact frequency reference based on Doppler-free MTS of molecular iodine at 532 nm, which is optimized for autonomous operation onboard a TEXUS sounding rocket starting fall 2017. Utilizing an externally frequency-doubled ECDL MOPA system, the JOKARUS mission poses new challenges on the automatization and reliable operation in harsh environments as well as providing a proof of concept for spaceborne operation. In this poster, we focus on system control and autonomy concepts as well as their possible merit for controlling similar optical clock setups.
