Abstract

The laser ablation characteristics of the procine menisci by the various laser irradiations were studied. We employed nine laser wavelengthes from ultraviolet(UV) region to infrared(IR) region, pulsed or continuous wave (cw). All laser irradiation experiments were performed in vitro with a fixed laser beam in air. The ablation rate and damaged layer thickness were measured. In order to compare the ablation characteristics of various laser wavelengths at the same condition, the laser irradiation energy density was kept constant. This study will investigate if the ablation characteristics depends on the wavelength of lasers and on emission mode (pulsed or cw). We expect that this study contribute to the progress in arthroscopic laser meniscectomy.
