The authors simulated and accompanied by optical measurements various available design options for constructing output stages of laser medical equipment in light of possible implementations under certain limitations in the design, production and operation processes. The design option for a flexible optical fiber proposed by the authors is characterized by its manufacturability and structural simplicity, ensures effective, repeatable transformation of homogeneity in the beam and, most likely, allows for complex optimization. In the case of relevance of light spots in the form of elongated rectangles, it may be interesting to use a combination of individual parallel beams and lens assemblies. When removing the restriction of mandatory beam collimation, the use of channel waveguides as an aperture is of particular interest (both from the point of view of reducing optical radiation power losses and variability of the performance of output cascades of laser equipment).
The use of photoplethysmography allows an accurate assessment of the level of blood supply in inflammatory symptoms in patients with diabetes after tooth extraction, this method has the positive properties of non-invasiveness, high sensitivity and probabilistic ease of examination. Photon radiation has been shown to increase blood vessel wall elasticity, erythrocyte elasticity, blood oxygen transport function, cell membrane activity, accelerate tissue regeneration, reduce lipid oxidation, and normalize blood rheology. The photon radiation of the "MultiSpectr-001" multispectral physiotherapy device has been shown to lead to anti-inflammatory, desensitizing, analgesic, antispasmodic, anti-edema effects, which was confirmed in this study in the treatment of diabetic patients.
