摘要：

We review the recent progress at LNE-SYRTE on an optical lattice clock using Sr atoms. We discuss the required lattice depth to cancel motional effects in such a clock and show that a relatively small lattice depth is sufficient provided the lattice is oriented vertically. We also demonstrate an accurate frequency measurement of the Sr clock transition with accuracy in the low 10(-15) range. Finally, we describe a new non-destructive method to detect the atoms in the clock and discuss the expected associated improvement in the frequency stability of the clock.
