| 摘 要： | 在液芯光纤内产生共振和预共振喇曼效应,喇曼光谱强度可以大幅度提高,最高可达109倍.本文介绍获得光纤(预)共振喇曼光谱的可行性、实验及实验结果.用远离吸收带的激光激发获得了α甲基吡啶预共振喇曼光谱.用小功率激光(0.8mW)、低浓度溶液(9.6×1012mol/L)还获得了β叶红素在CS2中的共振喇曼光谱.

| Abstract: | The resonance and preresonance Raman effect are produced in liquidcore optical fibers,enhancing the Raman spectral intensity by 109 times.The feasibility and experiment method for obtaining resonance and preresonance Raman spectra in liquidcore optical fiber are discussed.The preresonance Raman spectra of α-picoline have been obtained with the excitation laser at 514.5, 488.0and 454.5 nm respectively.The exciting wavelength is longer than that of the absorption band of α-picoline molecules.The resonance Raman spectra of β-carotene in CS2 have been obtained with the less excitation power (0.80mW),and the resonance Raman spectra of low concentration sample (3.4×10-13mol/L) have been also obtained. |
