Abstract
Pulsed or continuous surgical lasers may be used to achieve ablation with minimal thermal damage. The possible applications of surgical lasers range from resurfacing treatments to vaporization of numerous benign dermatological lesions. CO2 (10,600-nm) and Er:YAG (2940-nm) lasers emit in the far-infrared spectrum. Surgical laser was introduced in the past as a surgical tool capable of vaporizing tissue. Side effects may present as hypertrophic or atrophic scars or hypo- and hyperpigmentation, often reversible.
