Abstract

Coagulation of egg white of Nd:YAG and CO2 laser beams was filmed to illustrate the thermal effect of their radiation and the role of internal scattering caused by the increased structurization of the medium in its nontransparent phase, typical of practically all biological tissue. The purpose was a vivid demonstration of the range of necrosis attainable with these two lasers in surgical and endoscopic applications.
