laser duration/ms damage appearance 0～100 first-degree injure White coagulation spots appear on the skin epidermis, and the epidermis is flat 150～210 second-degree injure Blisters appear on the skin epidermis, with raised white coagulation spots 280～550 third-degree injure The epidermis of the skin is slightly vaporized, the dermis is degenerated, and shallow pit-like light red blood spots 660～ $ \infty $ fourth-degree injure The skin epidermis and superficial dermis are vaporized, accompanied by exudation of tissue fluid, eschars appear on the edges of the wound, and deep pit-like crimson blood spots
