Paper Abstract

A new model of low intensity laser irradiation action (LILI) on biological objects on cell level was suggested. Up to this model the effect of LILI action is a result of that fact that laser light irradiation due to it coherence can obtain periodical character (interference picture or speckle-structure) with small enough periods of dark and light parts changing comparable with cell or cell organelles sizes. In this conditions inhomogeneous light absorption can lead to electrical field appearance (Dember effect), which can change the character of photostimulated reactions and change membrane charge condition either of cell itself or of its organelles, that is lead to cell life cycle shifts.
