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 of high gradient illumination
an electrical field can appear (Dember effect), which is able to change the character
of photostimulated reactions and membrane charge conditions either of cell itself or of its
organelles, that leads to cell life cycle shifts.
