Abstract:

A new method was proposed to prepare excited coherent states and two-order excited coherent states, which is based on the interaction of atom inside high-Q cavity with a traveling wave light field. Compared with other presented methods, this method has some merits such as the perturbation theory is not used and one step preparation is only taken except for the final measurement. However, the success probability for this method is only 50%.

Key words: quantum optics, excited coherent states, high-Q cavity, traveling wave light field
