摘要
采用光场的量子理论导出了自由运转双模激光场强度起伏的噪声功率密度谱及其时谱公式，重点分析讨论了双模激光场的量子统计特性及其拍频噪声的时谱特性和频率调谐特性。研究发现双模激光拍频噪声的时谱特性也可用于双模激光的稳频稳幅。
Based on quantum theory of light, the noise power density spectrum and its timespectrum formula of the intensity fluctuation of a two-mode laser are derived. Quantum statistical properties of a two-mode laser and its time-spectrum characteristics as well as the frequency tuning features of the frequency beat noise are analyzed and discussed.The study shows that the time-spectrum characteristics of the frequency beat noise of a two-mode laser can be applied to the frequency and power stabilization of two-mode lasers
