在零差和外差迈克尔逊干涉仪中，随着光程差的变化，重复观察到静态干涉条纹。利用腔内声光可调谐滤波器（AOTF）的电调谐钛宝石激光器的这种独特的相干特性，揭示了激光场的频率结构和动力学特性。在不同光程的外差干涉仪中发生的静态干涉表明腔内光场的后向散射，表明腔内AOTF中发生了布里渊增强的四波混频。
Static interference fringes were observed repeatedly with changes of path difference in both homodyne and heterodyne Michelson interferometers. This unique coherence property of an electronically tuned Ti:sapphire laser with an intracavity acousto-optic tunable filter (AOTF) has revealed the frequency structure and dynamics of the laser field. The fact that static interference occurred in a heterodyne interferometer with unequal path lengths indicates backscattering of the intracavity laser field, suggesting that Brillouin-enhanced four-wave mixing occurs in the intracavity AOTF.
