Future space missions related to fundamental science, earth observation, and navigation and ranging require ultra-stable optical frequency references. Iodine references for laser stabilization have the potential to be developed space compatible on a relatively short time scale, while featuring frequency stabilities superior to other references like hydrogen masers.
We present a semi-monolithic, glass ceramic setup realized with an adhesive bonding technology, featuring a frequency stability of 8· 10−15 at 1 s averaging down to 2· 10−15 at 100 s.
Further, we report on the development of an engineering model utilizing a compact multi-pass gas cell. This setup will undergo environmental testing, including vibration tests and thermal cycling.
