Abstract

Ablation of hard biological tissue using XeCl-excimer lasers (wavelength 308 nm) yielded promising results. The 308 nm radiation was guided by tapered quartz fibers with core diameters of 400 - 1000 micrometers . Applying pulse energy of up to 70 mJ (pulse duration 28 ns, 60 ns, 300 ns) at different repetition rates, we found no noticeable thermal damage. The samples were immersed in water during irradiation. Bone specimens cut by the excimer laser did not show any melted hydroxylapatite crystals as described in the CO₂-cutting experiments performed by HORCH (4). The gross, histological, and scanning electron microscope examination of cuts and bore holes produced by excimer laser ablation of meniscus and bone tissue will be presented.
