摘　　要：传统测量激光波长的方法多用到一些精密度高、操作复杂的仪器,给实际应用带来许多不便。给出一种使用普通钢尺简便地“量”出激光波长的新方法,并将实验结果与衍射光栅测量激光波长的结果进行了比较,得出该方法同样具有较高的精确度,这是一种简便易行的测量激光波长的途径。The traditional way of measuring laser＇s wavelength always requires some accurate and complicated instruments, which brings much trouble to the application. This paper introduces the method of measuring laser＇s wavelength handily by employing a steel ruler. In addition, it compares the result with the consequence of using diffraction grating to measure the wavelength of laser. It is found that this method also has better accuracy, thus a new way to measure laser＇s wavelength is discovered.
