ABSTRACT:
A process for destroying relatively deep formations of unwanted sub-epidermal tissue by heating water in the formations with a laser to denature proteins therein. In an exemplary embodiment, a laser beam is operated to irradiate a target region of highly vascularized dermal tissue in a blood-circulating living being, such as a human. The laser light preferably has a wavelength of about 1.45-1.68 .mu.m. This operating parameter provides the laser beam with a low enough water absorption coefficient to facilitate adequate penetration in to the target area while still providing enough energy to heat water to a temperature capable of spatially conforming vascularized tissue in the target area.
