Annotation. This paper presents the modules of mobile and portable optical frequency references based on cold ytterbium atoms, developed at FSUE “VNIIFTRI”. The aim of this work is to improve such characteristics of an optical frequency standard as compactness, weight, energy efficiency, while maintaining the values of the relative stability and frequency accuracy of laboratory optical lattice clocks.

Key words: optical lattice clock, ytterbium, frequency, cold atoms.
