Mid-IR Laser Applications in Medicine

This chapter reviews medical applications of a variety of mid-infrared lasers. These applications are based on strong absorption of laser light in human tissue due to the presence of naturally occurring chromophores, specific and unspecific absorbers. Medically relevant laser-tissue interactions are described. Experimental data, obtained with free electron lasers describe photoablation quantitatively in the mid-IR as well as collateral adverse effects. Feedback technologies for online therapy control are presented; they enhance the selectivity of the laser—tissue interaction. Typical medical and surgical applications in gynecology, otorhinolaryngology, neurosurgery, dermatology, urology, dental surgery, ophthalmology and cardiovascular surgery are briefly summarized.
