| 摘 要： | 对采用棱镜耦合器的全反射棱镜式环形激光器的耦合输出特性进行了理论研究, 导出了有“楔形”间隙的棱镜耦合器的反射系数和透射系数表达式, 给出了反射率和透过率随“楔形”间隙高度变化的理论计算曲线, 进而研究了有关材料选取、腔内振荡分量的选取及减小棱镜耦合器对环形激光腔内模式的影响等问题. 这些研究对于全反射棱镜式环形激光器在激光陀螺、激光角速度传感器等实际应用中有重要意义.

| Abstract: | A way is studied to obtain output laser from ring laser with total reflection prisms by prism coupler. The expressions of the reflection coefficient and the transmission coefficient of the prism coupler constructed by cuniform clearance are deduced in theory, furthermore the theoretical curve of the reflectivity and the transmittivity VS the height of the cuniform clearance showed. Problems ,such as selection of the corresponding stuff, selection of the surge ponderance in the cavity and the influence of the minishing prism couplers on the mode of the ring laser cavity are discussed. The study is considerably important for the laser gyros consist of total prisms in practical application as laser gyro and laser angle speed sensor. |
