ABSTRACT:
A hand-held, non-invasive cutting device is configured to cut a fiber-like element, such as animal or human hair projecting from the surface of a medium, such as body skin, without exposing the user to the cutting beam. The device exterior is shaped to be readily placed against the surface of the body and has an aperture that accommodates passage of the hair to be cut into an interior region of the housing. The housing includes an optical energy beam director that directs a beam of optical energy, such as a laser beam generated by an external or internal laser, through an interior cutting zone, and onto the inserted element, thereby severing or vaporizing the element. Because the laser beam is aligned with and parallel to the longitudinal direction of the cutting window, then regardless of where it is inserted in the cutting window, the element will be cut by the laser beam. In addition, the beam cannot exit the cutting window, so that the invention is non-invasive and safe for consumer use.
