The healing effect of low energy lasers is generally attributed to enhanced cell proliferation due to the irradiation. As it was not clear whether coherent irradiation is essential, we examined the effect of various wavelengths from non-coherent light sources, on fibroblast proliferation. We found that light at 540 and 600-900 nm significantly accelerates the mitosis of these cells. Moreover, we have found that the effect is not only energy-dose dependent but depends non-lineraly on the intensity of the light source.
