Laser radiation of sufficient intensity and wavelenghth exposure time will lead to irreversable damage to eye and skin The most common cause of laser hazard on tissue are of thermal in nature Thermal effects occurs when the laser radiation is absorbed by the skin and the intensity of the damage it can cause depends upon the rise in temperature it leads to in an organism and the duration of this heating process Depending on this temperature elevation different damage can occur they are Hyperthermia Coagulation and Ablation In hyperthermia the temperature rise of 41C for about ten minutes leads to cellular death In coagulation a tissue temperature between 50C and 100C for about 1s leads todessication whitening and retraction of tissues due to protein and collagen denaturation Tissues will afterwards be eliminated detersion processes and the wound will scar In ablation the temperatures is higher than 100C Due to this the cell and its elements evaporate within a relatively short time As mentioned earlier laser radiation of particular intensity for particular period of See Answer
