I will propose and demonstrate the control method to reach the ultimate stability of atomic clock. Instead of locking laser frequency to atomic frequency, I will aim to lock laser phase to the atomic Phase. This phase lock method has a potential to dramatically improve the stability of the laser and improve the precision spectroscopy.
