摘要
本文报道一台适用于连续可调谐激光器自动扫描控制的激光波长计．它由两组游标标准具ＶＥＴ（ＶｅｒｎｉｅｒＥｔａｌｏｎ）和一旋光单色仪ＯＡＭ（ＯｐｔｉｃａｌＡｃｔｉｖｉｔｙＭｏｎｏｃｈｒｏｍａｔｏｒ）组成，波长测量重复精度优于±５０ＭＨｚ，测量波段为０．４～１．２μｍ。文中给出了在０．９３μｍ附近实验结果。
In this paper,the principle of the VET(vernier etalon) and OAM(Optical Activity Monochromator)is described and a method of measuring tunable laser wavelength by using multiple VETs proposed.A wavemeter for scanning laser is developed that consists of two VETs and an OAM. The wavemeter's available wavelength range is 0.4～1.2 μm,and its accuracy is experimentally proved to be better than 150 MRz.
