We report results from spectral measurements in the optical and near infrared region performed with a Fourier transform wavemeter. Characteristics of a variety of lasers and the performance of the wavemeter have been studied. The group of cw lasers measured in this work is comprised of a 1550-nm multimode diode laser, an 820-nm single-mode diode laser, a 594.5 nm dye laser, and He-Ne lasers at wavelengths of 1523, 633, and 543 nm. The Fourier transform wavemeter is powerful in multimode laser investigations and in long-term frequency stability determinations. The measurements show that the wavemeter also easily reveals very low power laser modes; it is suitable for the investigation of the single-mode purity of lasers. The line position uncertainty <10(-8) can be concluded in the measurements with polarization-stabilized 633- and 543-nm He-Ne lasers.
我们报告了使用傅里叶变换波长计在光学和近红外区域进行光谱测量的结果。研究了各种激光器的特性以及波长计的性能。在这项工作中测量的连续波激光器组包括一个1550纳米的多模二极管激光器、一个820纳米的单模二极管激光器、一个594.5纳米的染料激光器以及波长为1523、633和543纳米的氦氖激光器。傅里叶变换波长计在多模激光研究和长期频率稳定性测定方面功能强大。测量结果表明，该波长计还能轻松检测到极低功率的激光模式；它适用于研究激光器的单模纯度。在使用偏振稳定的633纳米和543纳米氦氖激光器进行的测量中，可以得出谱线位置不确定度<10(-8)。
