Recent advances in an aerosol-generation technique have permitted the accurate identification of optical resonance-mode features of micrometer-sized freely falling droplets for several different optical processes. Both input and output resonant features of fluorescence and lasing from dye-doped microdroplets were assigned to specific spherical cavity modes by using two independent procedures: (1) by matching observed fixed-angle elastic laser light scattering as a function of droplet size to calculated scattering intensities from the Lorenz-Mie theory, and (2) by matching observed resonance peaks to computed cavity-mode positions by automated correlation. Agreement between these two complementary techniques establishes high confidence in the resulting mode identifications. Assignments of observed emission peaks provide insight into droplet-emission mechanisms.
一种气溶胶生成技术的最新进展使得能够针对几种不同的光学过程准确识别微米级自由下落液滴的光学共振模式特征。通过使用两种独立的方法，将掺杂染料的微滴的荧光和激光发射的输入和输出共振特征分配给特定的球形腔模式：（1）将观察到的作为液滴尺寸函数的固定角度弹性激光散射与根据洛伦兹 - 米理论计算的散射强度进行匹配；（2）通过自动关联将观察到的共振峰与计算出的腔模式位置进行匹配。这两种互补技术之间的一致性为最终的模式识别建立了高度的可信度。观察到的发射峰的归属有助于深入了解液滴发射机制。
