Real-time gratings in photosynthetic reaction centers

摘要

The results of investigations of real-time gratings recording in lightsensitive medium of photosynthetic reaction centers that have absorption bands in near IR are presented. Investigations were carried out using low-intensity semiconductor lasers of different wavelengths. The contribution of absorption and dispersive components to grating is evaluated. The maximum diffraction efficiency value was 0.05%. The spatial-frequency dependence of grating efficiency is investigated.
