摘　　要：激光二极管（ＬＤ）抽运的固体激光器可用于光学计量、长度测量、相干光通信、激光雷达等方面，高精度应用要求激光器的频率稳定。碘分子在５３２ｎｍ附近有上百条强的吸收谱线，采用单频Ｎｄ：ＹＶＯ４／ＫＴＰ激光对碘的一些吸收谱线作了观测，并进行了激光频率稳定的研究，这些吸收谱线是１９９７年９月国际米定义咨询委员会（ＣＣＤＭ）推荐作为频标的９组５３２ｎｍ碘吸收谱线之外的新的参考谱线。Diode pumped solid state laser can be used to optical metrology,length measurements,coherent optics communication and laser radar,the high precision applications need the laser frequency stabilization. Molecular iodine has several hundred strong absorption lines near 532nm,several absorption lines were observed by using single frequeny Nd:YVO 4/KTP laser. There are new absorption lines which are not included in the nine groups recommended by CCDM in 1997.The wavelengths of these lines have been measured and the frequency stabilization investigated.
