非弹性散射使人们对最近关于光的安德森局域化的说法提出了质疑
Inelastic scattering puts in question recent claims of Anderson localization of light
摘要:
无序光学系统中的非线性效应和安德森局域化之间的相互作用最近引起了人们极大的兴趣,并且在其中闭合的多重散射环具有增强强度的随机激光的作用中是重要的。由于二氧化钛的光学非线性可以提供有价值的信息,在强散射粉末的光传输的性质,我们研究了这些影响,在一个扩展的实验和理论研究(待出版)。现在Scheffold和Wiersma已经...
英文摘要:
The interplay between nonlinear effects and Anderson localization in disordered optical fibres1 has recently attracted great interest, and it is important in the action of random lasers in which closed multiple scattering loops have enhanced intensity. As optical nonlinearities in TiO2 can give valuable information on the nature of light transport in strongly scattering powders, we studied these effects in an extended experimental and theoretical investigation (to be published). Now, Scheffold and Wiersma have ...
