用钢尺测量氦氖激光的波长

本文将钢尺作为一反射光栅的模型,较精确地、简便地＂量＂出氦氖激光的波长。并将实验结果与He-Ne激光的标准波长进行了比较,得出该方法具有较高的精确度,这是一种简便易行的测量激光波长的方法。

This paper introduces the method of measuring He--No laser wavelength accurately and handily by using a steel ruler as a diffraction grating model. In addition, it compares the result with normal He-Ne laser wavelength. It is found that this method also has better accuracy,thus a new way to measure laserg laser wavelength is discovered.
