Abstract

The action of laser radiation on arbitrary selected points of skin in the wavelength range 440 - 1060 nm and power range 40 mW - 4 W caused threshold and near threshold skin sensations. The warm sensations and skin pain were observed. The skin pain sensations are probably related to the radiation action on free nerve endings in the epidermis (specific skin pain) or upon the receptor system situated under the epidermis (nonspecific skin pain). The warm sensations are related to the radiation action on temperature-sensitive points of skin. The dependence of stimulus intensity on its duration for the threshold thermal sensations was revealed.
