Three types of lesions produced by argon laser micro‐irradiation of single mitochondria are described. A correlation between lesion severity and optical phase density and/or laser output power was observed. Cell survival was generally not affected by mitochondrial irradiation. As many as ten mitochondria were irradiated without cell death resulting. Absorption of the laser radiation was attributed to the natural chromophores, cytochromes c and c 1 .
