According to the quantum theory of the coherence of light field, the second order coherence g ~ (2) (z) and the time spectrum formula of the dual-mode laser field are derived and the results under three special cases are given. The second order quantum coherence and its time-frequency characteristics of the laser field reveal the periodicity and photon anti-correlation effect of the birefringent laser field g ~ (1) (z) Possible applications of features.
