Stable optical frequency references are a key component in future missions based on quantum sensors testing Einsteins equivalence principle or long baseline interferometers for gravitational wave detection. In this talk, we present JOKARUS: A simple and compact diode laser based frequency reference, stabilized to an optical transition in iodine at 532 nm. Our frequency reference aims to exceed the performance required for space missions such as LISA and GRACE follow on, and will be operated on a sounding rocket flight in Fall 2017 to demonstrate its technological maturity.
The design of our reference system, including diode laser source, gas cell assembly and electronics is presented in detail. JOKARUS is based on the heritage of three successful sounding rocket missions and is adaptable to various wavelengths to reach narrow optical transitions.
