摘要
分析了ＵＲ９０环形非稳腔（ＵｎｓｔａｂｌｅＲｅｓｏｎａｔｏｒｓｗｉｔｈ９０°ＢｅａｍＲｏｔａｔｉｏｎ）正向模和反向模的几何特性，讨论了反向模无阻挡时的振荡条件，并导出了理想ＵＲ９０环形非稳腔的光线追述方程，考查了此腔对激光增益介质的空间自平均效应。
Geometric properties of the forward and reverse modes of unstable resonators with 90°beam rotation (UR90) are analyzed. Requirements for reverse mode nonstopping oscillation are discussed. The ray tracing equations of the ideal UR90 are obtained. Sauce self-average effect for laser gain medium is investigsted.
