我们研究了拉曼光谱作为激光遥感工具监测溶解在水中的气体和气泡的适用性。用倍频Q开关Nd：YAG激光（532 nm）照射空气泵产生的CO2气泡。检测到来自CO2的1383 cm-1和来自水的1645 cm-1处的拉曼信号。结果表明，CO2/H2O拉曼信号比依赖于CO2气泡速率。
We examined the applicability of Raman spectroscopy as a laser remote sensing tool for monitoring the gases dissolved in water and gas bubbles. A frequency doubled Q-switched Nd:YAG laser (532 nm) is irradiated to CO2 gas bubbles generated by an air pump. The Raman signals at 1383 cm-1 from CO2 and 1645 cm-1 from water were detected. It has been shown that the CO2/H2O Raman signal ratio is dependent on the CO2 bubble rate.
