摘要
采用光场的量子理论导出了双模Ｈｅ－Ｎｅ激光场二阶相干度ｇ（２）（τ）的时谱公式，讨论了ｇ（２）（τ）的周期性、时谱特性和光子反相关效应，并在分析其频率调谐特性的基础上，探讨了双模激光场ｇ（２）（τ）的时谱特性在双模激光线宽ΔνＤ的测量和双模激光稳频稳幅中的可能应用。
In this paper,the time-spectrum formula of the second-order coherence degree g(2)(τ) of a two-mode He-Ne laser is derived,based on the quantum theory of the light.The periodicity, time-spectrum characteristics and photons anticorrelation effect of g(2> (τ)are studied. According to the analysis of g(2)(τ) tuning characteristics,we discussed the possible application of g(2)(τ) time-spectrum characteristics in two-mode laser field for laser linewidth measurement,and frequency and power stabilization of a two- mode laser.
