Title:

 Precision laser spectroscopy of simple atoms

Abstract:

      Precision laser spectroscopy of simple atoms, e.g. hydrogen, helium and lithium, has 
played important role in testing QED calculations and probing atomic nuclei. Recent 
developments utilizing novel methods have opened up new possibilities for precision 
spectroscopy. These techniques include, for example, the use of laser-cooled atoms and 
the application of femto-second optical frequency combs.
In this talk, I will first review several precision measurements that had led to great 
physics discoveries. I then will report and summarize our spectroscopic results of 
helium low-lying states, which were completed during the past few years in NTHU. Our 
recent progress in Rydberg two-photon spectroscopy will also be discussed.
