SUMMARY:Optical Atomic Clocks:  A New Era of Precision Timekeeping\, P
 hysics Department Colloquium\, Chris Oates\, NIST-Boulder
DESCRIPTION:The past decade has seen a revolution in atomic clocks tha
 t has advanced clock performance by more than two orders of magnitude.
   These new clocks\, based on lasers stabilized to narrow optical tran
 sitions in trapped ions or atoms\, use femtosecond lasers to link up w
 ith microwave or other optical clocks.  I will describe our research o
 n clocks based on neutral Yb atoms confined in an optical lattice\, an
 d highlight the key physical effects that need to be considered in opt
 ical clock design.  Finally\, I will highlight recent breakthroughs an
 d show how optical clocks are used in tests of fundamental physics as 
 well as precision timekeeping applications.
