subminiatur treatment laser device for biostimulation of organic tissue

摘要

An apparatus for the biostimulation and treatment of organic tissue is described, which apparatus is distinguished by its minimal size with a housing volume of approximately 50 cm3 and a short focal distance of the focused laser radiation (8). Provided in the beam path of the apparatus is at least one convex lens (2) which in terms of function is used for adjustable focusing between the laser radiation outlet opening and the interior of the housing. The laser is a cw diode laser (1) in the visible red to near infrared wave range (600-1100 nm), preferably 780 nm or 670 nm, with a design-related optical output of 0.5 to 10 mW, which in this apparatus, as a result of the great divergence of the laser beam in the further course of the beam, does not represent any risk to the human eye and at the same time has a relatively high power density (8) acting on the surface to be treated. A sensor ring (7) at the beam outlet opening assumes the function of a barrier. IMAGE
