Paper Abstract

We describe the results of preliminary studies on the interaction of continuous wave (cw), mid-infrared fiber laser light and soft biological tissues. An Er, Pr:ZBLAN fiber laser operating at a wavelength of 2.71 micrometer was used at 800 mW output power, a Tm-doped silica fiber laser at 1.98 micrometer provided up to 5 W output power, and a Yb:Er-doped silica fiber laser at 1.5 micrometer was used at 800 mW output power. Surface changes in tissue samples are described qualitatively and quantitatively, ablation velocity in tissue is measured, where observed, at the 800 mW power level, and sample sections are described with reference to histologically recognizable markers of thermal damage. The basic science described prepares the way toward ultimate clinical evaluations and applications of these new laser sources.
