The paper evaluates the possibility of using the indicator of the amount of chlorophyll a as an indicator of the light supply of green algae and cyanobacteria cultures. The study was conducted on the culture of Acutodesmus dimorphus (green algae) and Nostoc commune (cyanobacteria). They studied the effect of lasers that generate light waves of 405, 532, and 650 nm for different durations on the accumulation of chlorophyll a. It was noted that the amount of chlorophyll a in the biomass of the studied crops varies depending on the wavelength of light and the duration of irradiation. As the duration of irradiation increases, the content of chlorophyll a in the biomass of the studied objects decreases.
