液芯光纤可以使拉曼光谱强度提高103倍。将液芯光纤既作为样品池又作为前置放大系统,研制成功了体积小、重量轻、成本低、灵敏度高的小型拉曼光谱仪。结果表明:通过对液体及溶在液体中的样品进行自发拉曼光谱、共振拉曼光谱的测量,获得了理想的拉曼光谱。
Liquid core optical fiber Raman spectrum intensity can be increased 103 times. The liquid core optical fiber both as a sample cell and pre-amplification system, the successful development of small size, light weight, low cost, high sensitivity small Raman spectrometer. The results show that the ideal Raman spectrum is obtained by measuring Raman spectra and resonance Raman spectra of liquid and dissolved samples.
