A method is disclosed for substantially cutting and cauterizing tissue during a surgical procedure. The method involves using a first laser beam to irradiate a first area. The first laser beam is configured in intensity and duration to cut the tissue within the first area, and further causes a temporary increase in an absorptivity of tissue in a second area in proximity to the first area. A second laser beam is used to irradiate the second area while the temporary increase in absorptivity is occurring. The second laser beam has a different intensity than the first laser beam and cauterizes tissue within the second area substantially simultaneously with the cutting of the tissue in the first area.
