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.

染料掺杂微球发出的激光是通过荧光染料分子和形态依赖共振之间的耦合来进行的。以苯基三乙氧基硅烷（PTES）为起始材料，通过溶胶-凝胶技术制备了罗丹明6G掺杂的有机-无机杂化材料球形颗粒。通过泵浦532 nm波长的脉冲激光，从直径4-6 mm的颗粒中确认了598 nm波长的强激光发射。由于球形空腔结构需要颗粒尺寸控制、良好的圆形度、光滑的表面，在这项研究中，研究了制备球形颗粒的形成技术。制备染料掺杂颗粒的工艺步骤由两个主要过程组成； (1) PTES的水解和聚合，以及(2)液滴的固化。对于第二个过程，开发了两种制造染料掺杂微球的复杂技术：（a）液相乳液技术，（b）气相振动孔板技术。特别是振动孔板技术使我们能够获得光学腔结构的单分散微球。
