摘　　要：针对低压汞灯谱线能量弱且量值无法溯源的难题,本文以1 064 nm单块固体环形激光器作为基频光,经过两次倍频分别得到532 nm、266 nm激光,通过调制转移光谱技术将532 nm激光频率锁定在碘分子超精细谱线上,以此为基础对光栅型光谱仪的波长准确度进行校准。实验结果表明,稳频波长源输出的三波长具有严格的倍数关系,能够准确有效地对光栅型光谱仪波长准确度进行校准,具有很好的实际应用价值。The spectrum power of low-pressure mercury is weak, and the spectral lines cannot be traceable to national standard. Using SHG and FHG technique, the laser at 532nm and 266nm was obtained based on 1064nm single solid-state ring laser. Using modulation transfer spectroscopy, the frequency of the 532nm laser was stabilized at 10 hyperfine Spectra of 127I R （56）32-0. The wavelength accuracy of grating spectrograph was calibrated. The experiment results prove that the wavelengths of frequency stabilized wavelength source have strict multiple relationship, and the wavelength accuracy of grating spectrograph can be calibrated accurately and effectively. So this technique has good application value.
