摘要: 提出了气相光声激光磁共振的新方法,并作了理论解释.分别在光强调制和激光腔频调制下,首次测到了NO2的光声激光磁共振谱.其灵敏度很高,在低浓度和高气压下优点尤为明显.

Abstract: A new method is proposed in this paper, which is photoacoustics laser magnetic resonance (PALMR) in gas phase. PALMR spectrum of NO2 was observed for the first time in light intensity modulation and laser cavity freqnency modulation. The method has high sensitivity, especially, in low density and high pressure. Although the experiment was done in mid-infrared, this method may also be suitable for far-infrared.
