Accurate measurements of the wavenumbers of more than 100 lines in the nu(3) band of ozone have been made using a tunable semiconductor diode laser and a temperature-stabilized germanium etalon. The accuracy for the line centers is estimated to be within 3-10 MHz and compares well with the accuracy attained using more complicated heterodyne techniques. The relevance of these results to ozone monitoring instruments based on CO(2) lasers is discussed. The tunability of the diode laser is also exploited to monitor ambient concentrations of ozone in the presence of interfering molecular species. A detection sensitivity of ~0.5 ppb of ozone is demonstrated.
利用可调谐半导体二极管激光器和温度稳定的锗标准具，对臭氧ν(3)带中100多条谱线的波数进行了精确测量。谱线中心的精度估计在3 - 10兆赫兹以内，与使用更复杂的外差技术所达到的精度相当。讨论了这些结果与基于二氧化碳激光器的臭氧监测仪器的相关性。还利用二极管激光器的可调谐性在存在干扰分子物种的情况下监测环境中的臭氧浓度。展示了约0.5 ppb臭氧的检测灵敏度。
