Abstract
A hair cutting device for cutting hair on a body of a subject includes a laser light source, and a light guiding element for guiding light from the light source to the cutting element. The cutting element includes an optical waveguide for receiving light from the light guiding element. The light guiding element has a tapered section in which a diameter of the light guiding element reduces from a light source side diameter to a cutting element side diameter. A portion of a sidewall of the optical waveguide of the cutting element forms a cutting face for contacting hair.
