摘要
采用超荧光光源(SFS)搭建了一个新型的气体吸收谱线测量装置,成功实现了对13.332 kPa气压下H13C14N(HCN)气体分子2ν3振动带精细结构的准确测量。分析了双程后向(DPB)结构的SFS和HCN分子的结构及振动转动模式,所采用的SFS在2 mW输出功率下,激发了2ν3振动带J=0-27的转动能级,输出谱在波长1525.3-1560.3 nm之间平坦度小于1 dBm,可以直接覆盖测量50多条振转谱线,无需多次扫描和数据拟合。利用了SFS高亮度和宽谱的特性,与常用的窄线宽可调谐激光器扫描法和经典吸收法比较,结构简单,成本低,可以很方便地实现实验室条件下气体分子精细结构的研究。
Abstract
An improved gas absorption spectrum measurement setup is proposed. A super fluoresent source (SFS) has been used to measure the infrared vibration-rotation spectrum of 2ν3 band of H13C14N (HCN) molecule successfully. The configuration of double pass backward (DFB) type SFS, the molecule structure of HCN and fundamental modes of oscillation were introduced, the SFS output power was fixed at 2mW, J=0-27 rotation energy levels were excited. The flatness of spectrum is less than 1 dBm from 1525.3 to 1560.3nm, and over fifty absorption lines are measured directly without scanning and data fitting. The high brightness and wideband properties are utilized in the scheme, the structure is simpler, and the cost is cheaper than traditional measurement method, and it can be used to study the molecule fine structure in the laboratory.
