染料和光敏染料的漂白和促进回收
Bleaching and stimulated recovery of dyes and of photo-cantilevers
摘要：
我们研究如何强烈的光束可以深入到高吸收介质的非线性，光漂白过程。染料基态的刺激恢复的作用可以是重要的，并划定。这种非线性吸收过程的分析一般适用于发色团受到辐射的情况，例如在生物学中。我们研究了由大量染料负载的光致固体制成的悬臂梁的弯曲的影响，所述悬臂梁是对光具有大的机械反应的玻璃和弹性体。特别是，我们描述了弯曲的杠杆充分吸收，他们不会弯曲，如果比尔定律适用。我们量化的光学产生的热量在确定机械响应的作用，并得出结论，在一般情况下，它是次要的重要性相比，光学效应。
英文摘要：
We examine how intense optical beams can penetrate deeply into highly absorbing media by a non-linear, photo-bleaching process. The role of stimulated recovery to the dye ground state can be important and is delineated. This analysis of non-linear absorption processes is applicable in general to situations where chromophores are irradiated, for instance in biology. We examine the implications for the bending of cantilevers made of heavily dye-loaded nematic photo-solids, that is nematic glasses and elastomers that have large mechanical reactions to light. In particular we describe the bending of cantilevers sufficiently absorbing that they would not bend if Beer's Law were applicable. We quantify the role of optically-generated heat in determining the mechanical response and conclude that in general it is minor in importance compared with optical effects.
