| 摘 要： | 多环端镜激光腔中各阶横模特性的一些计算结果表明:适当结构的这类新型腔与普通激光腔比较,可具有较大的横模选择性与基横模光斑半径.不考虑开孔衍射的准几何光学理论不适用于这类新型腔.新型腔可使某些单横模工作激光器的最佳输出功率约为应用相应的普通激光腔时的两倍或两倍以上.

| Abstract: | The results of calculations for characteristics of various order transverse modes in resonators with multi-ring end-reflectors show that The selectivity of transverse modes, and the widths of the foundamental transverse modes in proper structures of the new kind of resonators can all be greater than those in the corresponding common laser resonators. The quasi-geometric optical theory ignoring the aperture diffraction effects can not be suited for these new resonators. It is shown that the optimal out-put powers of lasers of new kind of resonators operating with single transverse modes are about equal to or greater than the double of that can be obtained from corresponding common laser resonators. |
