Hazards associated with viewing the incandescence of lased tissue.
Interaction of the CO2 laser beam with tissue often causes brief incandescence, which appears as a series of bright localized flashes when viewed either directly or through the optics of a colposcope or operating microscope.
A study has been carried out to establish if there is a hazard associated with viewing the incandescent flash.
A combined theoretical and experimental approach was undertaken to consider the situation presented by 20 W laser radiation on tissue.
It was concluded that viewing the incandescence from this situation did not constitute a hazard and that this conclusion could be extended to laser powers up to 100 W.
