激光溶胶的光散射特性

Light Scattering Characteristics of Laser Colloid

介绍了一种掺Nd_2O_3纳米颗粒的溶胶体系,对其光散射特性和消光系数进行了理论分析和数值模拟。结果表明,当溶胶体系中Nd原子的浓度为1.386×10^(20)cm^(-3)、Nd_2O_3纳米颗粒的半径为5 nm、相对折射率小于1.25时,对1064 nm波长激光的散射损耗不超过0.002 cm^(-1)。因此,掺Nd_2O_3纳米颗粒的溶胶体系可能是一种理想的激光介质。

A kind of colloid mixed with Nd2O3 nano-particles is introduced. The light scattering characteristics and the extinction coefficient are analyzed and simulated. When the Nd atom concentration is 1. 386 × 10^20 cm^-3, the radius of Nd2O3 nano-particles is about 5 nm and the relative refractive index is less than 1.25, the results show that the scattering loss of the laser colloid at 1064 nm wavelength is less than 0. 002 cm^-1. Therefore, the laser colloid with Nd2O3 nano-particles may be is a kind of excellent laser medium.
