The subject of this brief state-of-the-art research review is the rapidly developing field of optical frequency standards using optically and electromagnetically trapped ultracold atoms and ions. The primary emphasis is on the new spectroscopic techniques developed at the Institute of Laser Physics SB RAS to improve the stability and precision of current optical frequency standards.
