摘　　要：利用光参量振荡器产生的脉冲光研究了衰荡腔在不同条件下的衰减信号。实验表明，衰荡腔的输出信号会呈现复杂的调制。这些现象，有些可利用在谐振腔本征模理论基础上导出的公式来解释，另外一些可能是由于像散和畸变引起腔的横模分裂，从而导致复杂的模拍效应。The signals emitted from the ring down cavities under differnt conditions were investigated using pulsed light from an optical parametric oscillator. The ring down signals coupled with complicated modulations were observed in the experiment. Some of the mode frequencies can be explained by the formula deduced from the eigenmode theory of resonant cavity. It is proposed that the complicated mode beating was due to the slight splitting of the transverse mode owing to the astigmation and aberration of the ring down cavity optical system.
