Lasing from a dye-doped microsphere was performed from the coupling between fluorescent dye molecules and morphology-dependent-resonances. Using phenyl triethoxy silane (PTES) as a starting material, I made Rhodamine 6G-doped spherical particles of organic-inorganic hybrid material by sol-gel technique. From the particles of 4-6 mm in diameter, a strong laser emission at 598 nm wavelength was confirmed by pumping a pulse laser light of 532 nm wavelength.Since particle size control, good circularity, smooth surface are required for the spherical cavity structure, in this study, the formation techniques for preparing spherical particles have been investigated. Processing steps for preparing dye-doped particles are consisted of two major processes ; (1) Hydrolysis and polymerization of PTES, and (2) Solidification of liquid droplets. For the second process two elaborate techniques to make dye-doped microspheres were developed : (a) Emulsion technique in liquid phase, (b) Vibrating orifice technique in gas phase. Especially the vibrating orifice technique enables us to obtain monodispersed microspheres of optical cavity structure.

来自染料掺杂的微球的激光是通过荧光染料分子和形态依赖性共振之间的耦合进行的。使用苯基三乙氧基硅烷（PTE）作为起始材料，我通过Sol-Gel Technique制作了有机无机杂化材料的若丹明6G掺杂的球形颗粒。从直径为4-6毫米的颗粒中，通过泵送532 nm波长的脉冲激光灯来确认在598 nm波长处的强激光发射。在这项研究中，对球形腔结构进行了良好的颗粒尺寸控制，良好的循环表面需要光滑的表面。制备染料掺杂颗粒的处理步骤包括两个主要过程。 （1）PTE的水解和聚合，以及（2）液滴的固化。在第二个过程中，开发了两种详细的技术来制造染料掺杂的微球：（a）液相的乳液技术，（b）气相中的振动孔技术。特别是振动孔技术使我们能够获得光腔结构的单分散微球。
