• Currently lasers are used to destroy Birthmark and Lentigo in clinics of dermatology and plastic surgery. The aim of laser therapy is to destroy the target cells and not to harm the surrounding tissue. We have developed a new type of laser apparatus for removing only the pigmented lesions with laser scanning technology. The effects of a Nd:YVO4 laser (1064 nm) with a laser spot size of 30 gm in diameter was investigated by experiments with rats. As a result, the pigmented lesions were able to be removed but some scar tissues were formed. The thermometry during the laser irradiation was performed with an infrared thermal imaging camera. It was found that the temperature rise by laser irradiation reached the temperature that was high enough to cause a burn. Thus, to resolve this problem a new irradiation method in which the focused laser beam was scanned with each laser line 150 gm apart was proposed.
