迈克尔逊干涉仪专用He-Ne激光光源的自制与应用

The Design and Application of Specific He-Ne Laser Source for Michelson Interferometer

设计自制了迈克尔逊干涉仪专用激光光源并介绍了它的工作原理、关键的电气特性。该装置采用内腔式250mm氦氖激光管,使用倍压整流电路并配有高传输性光纤,让使用者在迈克尔逊干涉实验中能快速的将光路调整至等高、共轴状态,相较于传统方法提高了测量的准确性。

The specific laser source of 250 mm intracavity He-Ne laser tube for Michelson interferometer was developed. This paper introduces He-Ne laser machine＇s principle of operation and key electrical characteristic. By means of high speed optical fiber and voltage doubling rectifying circuit,which regulate each optical element accurately and quickly to coaxial and equal altitude in Michelson interferometer experiment. It was found that measurements with this device were more accurate than traditional method.
