摘要
通过对RhB/PMMA和Rh6G/PMMA染料薄膜的荧光光谱和放大自发辐射(ASE)光谱的实验测量和理论分析,研究了准波导结构染料薄膜的荧光光谱和ASE光谱特性。实验上采用连续激光和脉冲激光照射,分别测量准波导结构RhB/PMMA和Rh6G/PMMA染料薄膜的荧光光谱和ASE光谱,发现荧光峰和ASE峰随着染料掺杂浓度和薄膜厚度的增加产生红移;理论上考虑准波导结构下薄膜中染料的自吸收效应,类比激光器谐振腔模型,分析低阶导模传输的增益特性,获得了荧光光谱与ASE光谱中荧光峰和ASE峰对应波长与染料掺杂浓度的关系,数值计算与实验测量相吻合。结果表明,准波导结构下薄膜中染料自吸收效应导致荧光峰及ASE峰发生红移,改变染料掺杂浓度,可以在较大调谐范围实现ASE。
Abstract
The characteristics of the fluorescence spectra and amplified spontaneous emission (ASE) spectra of the RhB/PMMA and the Rh6G/PMMA films in the quasi-waveguides structure are experimentally measured and theoretically analyzed. By using of the radiation of the continue-wave laser and pulse laser, the fluorescence and ASE of the RhB/PMMA and the Rh6G/PMMA films are realized. It is found that the peaks of the fluorescence and ASE are shifted to longer wavelengths as the increase of the dye-doped concentrations and the film thicknesses. By analogy to the model of laser resonance cavity, the self-absorption effect of doped dyes and the gain amplifications of low-order guided modes transmitted in the dyes-doped films are explained for the quasi-waveguides structures and the relation of the wavelengths of fluorescence peak and ASE peak with the dye-doped concentration are obtained. The results show that the theoretical calculations are consistent with the experimental measurement. It is confirmed that the peak-shifts in the fluorescence spectra and ASE spectra are mainly attributed to the self-absorption effect of dye so that the wavelength of ASE peak can be tuned in wider range by the change of doped dye concentration.
