Abstract

Some results of the copper and gold vapor lasers and of helium-cadmium lasers used in medical practice are presented. The most in medical use copper vapor laser is commonly applied for low-intensity laser therapy and endoscopic surgery. A universal capability of dye lasers oscillating in 600 - 670 red region for excitation of the preparates used in photodynamic therapy is demonstrated. The copper vapor lasers are shown also to effectively coagulate pre- tumor neoplasms. A new method of laser beams shaping fitted to tumor configuration basing on quantum optical systems including image brightness amplifiers is described. Variability of the irradiating beam contrast is displayed, including the contrast inversion. Possibilities of the copper vapor lasers use for tumors drugless phototherapy and the two-step and two-stage methods of the photodynamic therapy are discussed. Some Russian medical systems based on the copper vapor lasers and dye lasers pumped by them are specified in parameters.
