DYNAMICS OF THE PHOTORESPONSE OF BLOOD TO RED LASER-RADIATION

Using the method of intracavity reflective laser refractometry, we per formed a real-time investigation of the photoresponse of blood to irra diation by a He-Ne laser at the wavelength of 0.63 mu m. It is demonst rated that the response of blood to irradiation is restricted to a tim e interval of several tenths of a second from the beginning of irradia tion. The stimulating therapeutic effect is caused by absorption of re d light by macromolecules that enter in formal elements of blood.
