【摘要】 提出了用多重游标标准具ＶＥＴ（ＶｅｒｎｉｅｒＥｔａｌｏｎ）测量连续可调谐激光器输出波长的原理，并用自行设计的两个ＶＥＴ和一台小型的光栅单色仪组成的波长计测量了ＣＲ８９９－２１型激光器８００ｎｍ处的输出波长，波长测量精度优于１×１０－６。在此基础上，设计了一种由三重游标标准具构成的新型激光波长计。更多还原

【Abstract】 The principle of measuring the wavelength of continuous wave tunable laser by using multiple vernier etalons is proposed.A wavemeter was constructed by two VETs and a simple grating monochromator and its accuracy is proved to be better than 1×10-6 by the experiment. Based on these,a novel compact wavemeter constructed by a triple VET was designed.更多还原
