Optical Lattice Clock : A Novel Tool for Precision Optical-Frequency Measurements(Current Topics)

Abstract

Recent progress in phase coherent optical frequency measurement based on SI second has brought about unprecedented significance for the development of frequency standards in optical region. We present an idea of "optical lattice clock" that allows to interrogate millions of quantum absorbers separately prepared in the Lamb-Dicke region. We discuss the implementation of light shift cancellation technique and demonstrate a high-resolution spectroscopy of strontium atoms trapped in a 1D optical lattice.
