Abstract
A significant advantage of Er:YAG and Ho:YAG laser radiation is that it can be transmitted efficiently by fibre, unlike that of the CO2 laser. The important characteristic of excisions made by these mid-infrared-beam lasers is the depth of coagulation beneath the excised surface. Intuitive physical arguments are developed to predict the coagulation depths, which are estimated to be 12μmand 650 μm for Er:YAG and Ho:YAG lesions respectively. These values are in agreement with derivations using more sophisticated physics by the same author elsewhere.
