Laser Irradiation of Tissue

  • A. J. Welch

Abstract

The rapid development of laser technology has provided the biomedical community with a variety of intense sources of electromagnetic radiation in the visible and infrared spectrum. When laser radiation strikes tissue, it absorbs a portion of the incident energy. The absorbed energy elevates the temperature of the tissue, and if the temperature increase is sufficiently high, irreversible damage, such as enzyme inactivation or protein denaturation, occurs. Further increases in the amount of energy absorbed may burn or even vaporize the tissue. The high-power densities that can be realized with the focused laser beam provide a unique surgical tool for cutting or destroying tissue.
