Abstract

Swine skin, muscle, liver, brain, myocardium and human cartilage, and arteriosclerotic plaque were irradiated at various power outputs with a Nd:YAG laser operating at 1.06 and 1.32μm. Nd:YAG at 1.06 exhibited the well-known coagulative effects with a high thermal component. Nd:YAG at 1.32μm, on the other hand, exhibited tissue evaporative and cutting effects not unlike those of the CO2 laser. Both lasers were delivered through optical fibers with 200-and 600-μm core diameters. These differences can be exploited for different clinical uses.
