Medical Laser

의료용 Laser

Characteristics and applications of three major types of lasers are discussed. They are chemical-metabolic, thermal destructive, and nonthermal mechanical lasers. The thermal destructive lasers ($CO_2$, Argon, and Nd:YAG) are especially explained in detail with regard to energy density, wavelength, fluence, stage of thermal destruction, and advantages of laser surgery. Excimer and Q-swiched lasers are discussed as nonthermal mechanical ones. Delivery system, optical fiber and articulated arm, is also discussed. Finally, recent advancements of medical laser are included in the conclusion.
