摘要

提出了一种利用光子阱和光导记录拉曼光谱信号放大的方法。利用铜蒸汽激光器产生的脉冲周期激光激发，研究了置于光子阱中的二氧化钛微粉的拉曼光谱。利用现有的光子阱和光纤技术，可以在室温下在二氧化钛微结构中实现组合乳光模式。这种模式表现为拉曼散射强度在二次辐射光谱中的异常增加。

Effect of Raman Opalescence on Titanium Dioxide Micropowders Under Pulse-Periodic Laser Excitation

A method is proposed for recording the amplification of Raman spectral signals using photon traps and light guides. The Raman spectra of titanium dioxide micropowders placed in a photon trap were studied using pulse-periodic laser excitation generated by a copper vapor laser. A combination opalescence mode can be realized using existing photon traps and fiber-optic techniques in titanium dioxide microstructures at room temperature. This mode consists in an abnormal increase of the Raman scattering intensity into the secondary radiation spectra.
