q－相干态光场相位特性

Characterisitic of Phase of the Light Field of q -Glauber and q -Coherent States (E - 0, q -CS_s)

本文给出了ｑ变形光场Ｐｅｇｇ—Ｂａｒｎｅｔｔ相位定义，计算了ｑ－相干态，ｑ－奇偶相干态的相位分布函数及相位算符的期特值和相位的涨落，得出ｑ畸变参数决定相位分布函数及相位涨落的值．

In this paper a defination of q -phase of Pegg-Barnett isgiven. Phase probabitity distribution and phase variance of q - Glauber,q -coherent (E -0, q --CSs)are obtained by calculation. From the resultsq -refernces limit values of Pg (θm) and <(△Φq0)2> are also given.
