Abstract

Pulsed infrared lasers operating in the 3 µm wavelength region, where water exhibits a peak in its absorption spectrum, offer an interesting alternative to deep uv excimer lasers for controlled tissue ablation.¹ The short beam penetration depth in tissue restricts residual thermal damage to a relatively small zone, and there are advantages with this wavelength in terms of fiber deliverability and a low mutagenic threat.
