LIGHT AND LASER RADIATION IN MEDICINE

Abstract

Light and laser radiation in medicine. Physics of lasers and properties of laser radiation. interaction of laser radiation with biological tissues. Characteristics and parameters of laser radiation. modes of operation of laser radiation. Laser diagnostics, low-intensity and power therapy, surgery. the effect of laser radiation on soft tissues and bone Phototherapy is a method of physiotherapy, which consists in using, for therapeutic and prophylactic purposes, the energy of light from visible, infrared and ultraviolet rays from natural (sun) and artificial sources. At present, laser radiation, which does not exist in nature, can be attributed to phototherapy.

Only absorbed energy has a biological effect. Visible rays are of hygienic importance, although light sources provide both visible and infrared rays, sometimes all three types of radiation.
