We present a compact iodine frequency reference developed with respect to space applications, which is realized on a fused silica baseplate using an adhesive bonding method and a special designed multipass absorbtion cell.
A Nd:YAG laser system featuring waveguide SHG modules is stabilized to hyperfine transitions in I2 at 532 nm by means of the modulation transfer spectroscopy technique with a relative stability of 10−15 at several seconds of averaging time. This system can be a useful optical frequency reference for future space missions related to fundamental science, earth observation, and navigation and ranging using 1064 nm laser technology.
We report on environmental tests of the setup including thermal
cycling and vibrational test required for space qualification.
