Abstract
Impacts of the laser on living tissue show significant effects on blood vessels with either hemorrhage or thrombosis (clotting), or both. It was assumed that the red color absorbed the laser radiation. Our studies on fresh blood smears showed destruction of red cells even with low energy densities. These changes included swelling of the cell, blister formation and even complete vaporization. The energy densities for such changes in red cells of fresh smears were found by J. Goldman and P. Hornby to be in the range of 0.16 joules exit energy. It was noted that white cells in the same field showed little effect when these blood smears were stained after exposure. There was little effect on platelets unless dyed.
