One of the way of using external influence on increasing of organism-s growth and reproduction associated with electromagnetic impact on it. The interest in the study this effect is that it can-t be predicted. Due to these researches in progress of this work ability of effects of stimulating and inhibition of Chlorella vulgaris cells growth and reproduction were established. According to the reflection coefficient of the interface between air and misalignment of chlorella, it can be told that the power of incident radiation was about hundreds microwatt on square centimeter what is told about non-thermal effect. Effect of stimulation could be found on all of the investigated range and there was an explicit dependence of the effect from the frequency. The regulation of microalgae growth can be caused not by influence on the cells itself, but by the influence on the molecule of surrounding water was said. Received results as one of such effects steps could be taken in future.
