[Dermatological plastic surgery dye laser].

The paper deals with feasibility studies conducted to choose a laser for the treatment of vascular diseases causing skin hyperpigmentation. It describes a laser unit selectively acting on diseased vessels, which operates at a wavelength of 577 nm and at an energy density of 6-8 J/cm2 with pulse generation lasting at least 100 microseconds. In future the duration of pulse generation should be prolonged to 400 microseconds.
