摘    要:本文指出调Q红宝石激光器的单纵模选择是非常困难的。若激光器的两个相较透的纵模同时振荡,纵然我们用单脉冲一次照全息像,当再调时也会有干涉条纹出现。本文指出干涉条纹的出现实际上是相干长度呈周期性的表现。只要采取相应措施保证单纵模运转,就可以消除这种现象。本文还指出了提高相干长度的办法。

关 键 词:全息干涉条纹  选单纵模  双频振荡

Abstract:It is very difficult to select the single longitudinal mode in a ntby laser cavity. Interference fringes would appear ia the reconstructed image even though in making a hologram at a single exposure. These hologram interference fringes display the periodicity of coherence length of the laser. Certain procedures cam be adopted to avoid this situation and ensure single longitudinal mode operation. Hence all the interference fringes will be disappeared. The coherence of the, laser it also discussed in this paper.
Keywords:hologram interference fringes   to select the single longitudinal mode   two-frequency oscillation
