UMD: Lasers designed for dermatologic therapy using a solid-state ruby rod as active medium. These lasers emit light with a wavelength of 694 nm (red) that is usually delivered using a flexible fiberoptic cable; they are typically operated in pulsed and/or Q-switched modes. Ruby lasers are intended mainly for treatment of pigmented lesions, using selective thermal chemical dissociation by means of light (photothermolysis).
