Poster: Iodine frequency reference for space applications using a multipass absorption cell

Abstract

Future space missions related to fundamental science, earth observation, and navigation and ranging require ultra-stable optical frequency references. Besides optical cavities, iodine references for laser stabilization have the potential to be developed in terms of space compatibility on a relatively short time scale, while providing an absolute frequency reference. Here we present a semi-monolithic, glass ceramic setup realized with an adhesive bonding technology, featuring a special designed multipass absorption cell designed with respect to space applications, featuring a frequency (in)stability of 2·10-14 at 1 s integration time averaging down to 5·10-15 between 20 and 20.000 s. Furthermore, we report on environmental testing, including vibration tests and thermal cycling.
