Abstract :
A biophysical model is proposed which supplements existing ideas about the mechanism of low intensive IR laser radiation effects on a cellular biosystem. For the first time the model considers the multifrequency character of real laser radiation and takes into account the accompanied effect of periodical modulation for resonant absorption coefficient of laser light by cellular sensors (targets)-water dissolved oxygen or artificially introduced chromophoral (dye) biomolecules. Under a certain choice of laser spectrum parameters the multifrequency laser light affecting the cellular targets results in raising the millimeter wave components in the target thermalization energy spectrum. This effect is the same as due to direct cell excitation by pure millimeter waves and is able to cause well known resonant biological action effects of pure millimeter waves. The proposed model permits one to consider low intensive laser light with millimeter wave intensity modulation as a new and efficient type of combined biological effect both in millimeter and IR frequency ranges. A method and family of devices are proposed for application in biology, medicine and agriculture
