From: JOKARUS - design of a compact optical iodine frequency reference for a sounding rocket mission
Estimated frequency stability of JOKARUS in comparison to another iodine frequency reference (EBB) using an Nd:YAG laser. Frequency noise of the free-running Nd:YAG laser (blue) is suppressed by frequency stabilization to the EBB resulting in frequency noise depicted in green. The frequency noise of the ECDL is expected to be reduced to the frequency noise indicated by the red dashed line when locked to the JOKARUS spectroscopy module. The requirements on the laser frequency noise for missions like LISA and NGGM are shown in blue and yellow, respectively.
