The dose-response relationship for producing different grades of burns on skin produced by single Er-glass laser pulse were determined for energy densities within the range 0.5-35 J/cm2 and pulse duration 100 ns and 2.5 ms. The persistent lesions on skin were subdivided into four morphologically different groups vs. radiant exposure of laser pulses. Histological investigation were made at 1- and 3-days post-exposure. Different methods of tissue preparation were tried to obtain better contrast of laser induced changes in skin tissue. At the 1-day post-exposure we observed on the histological samples coagulation of surface tissue, epidermis and dermis of skin depending on radiant exposure. 3-days histological samples revealed tearing of tissue detrit and active epitalization of damaged tissue.
