Laser-Tissue Interactions Interactions of laser light with biological tissue vary with pulse
duration, intensity and wavelength of the radiation. They include photo-chemical,
thermal, mechanical and multi-photon phenomena. We study mechanisms of
interaction of pulsed lasers with biological cells and tissues including ·
Cellular and tissue hyperthermia (milliseconds to
seconds) ·
Dynamics of tissue coagulation (micro- to
milliseconds). ·
Explosive vaporization and cavitation (nano- to
microseconds) ·
Multi-photon ionization in liquids (femto- to
picoseconds) We develop applications of these interactions to: o
Minimally-traumatic
ocular laser therapy (retina and trabecular meshwork) o
Tissue dissection and ablation |
