摘　　要：介绍微腔研究理论的发展和微球腔中的光线量子论。测试了488 nm激光激发下掺铒磷酸盐玻璃微球的1 533 nm荧光光谱,分析其谱线中的形貌共振现象及形成机制,并将掺铒磷酸盐玻璃微球的荧光光谱和掺铒磷酸盐体玻璃的荧光光谱进行比较。从实验中得到了掺铒磷酸盐玻璃微球产生的单模振荡幅度。The development of microspherical cavity theory is introduced, and the microspherical cavity is analyzed with light quantum mechanics. The 1 533 nm fluorescence spectrum of the Er^3＋ doped phosphate glass microsphere （about 15 μm in diameter） was measured under laser excitation of 488 nm. The phenomenon of the morphology-dependent resonances of the fluorescence spectrum in the glass microsphere and its formation mechanism were observed and analyzed. The fluorescence spectra of the Er^3＋ doped phosphate glass microsphere were compared with those of corresponding bulk glass. The single-mode oscillation amplitude generated by the Er^3＋ doped phosphate glass microsphere was obtained in the experiment.
