Influence of light fluence on the attenuation coefficient of nonlinear optical absorbers with nanotubes and dyes

摘要

Optical absorbers can be used to attenuate laser radiation to a safe level. At the same time, it is necessary to ensure high transmission of nonhazardous low-intensity radiation and a sharply reduced transmission at high intensity. To achieve this basic requirement can be due to nonlinear optical effects. In addition, the developed absorbers can be added to the formation of three-dimensional tissue-engineered structures. Thus, it will be possible to control the thickness of the layer being formed.
