In our studies, we use the dye laser (dye) with the wavelength of 595 nm. The emitted energy at this wavelength (the laser is sometimes is called yellow laser) can fotocoagulate blood vessels. Suitably modified parameters of the energy intensity and the diameter of the spot permeate the vascular lesions’ treatment of the different diameter. In order to make the treatment safer and more comfortable on the patient’s skin is sprayed off (in automatic mode) a cryogen before, during and after the emission of the laser impulse. In such a way the skin surface layers are protected and the painful sensations are reduced. Usually, this type of laser is indicated for the treatment of angiomas, port-wine stains, facial spider veins (capillaries), rosacea, but it is often used with great success in the treatment of scars and warts.
