摘要:
There is provided a hair cutting device for cutting hair on a body of a subject, the hair cutting device comprising a light source for generating laser light at one or more specific wavelengths corresponding to wavelengths absorbed by one or more chromophores in hair and a cutting element that comprises an optical waveguide that is coupled to the light source to receive laser light, wherein a portion of a side wall of the optical waveguide forms a cutting face for contacting hair, and wherein at least at the cutting face the optical waveguide has a refractive index that is equal to or lower than the refractive index of hair and higher than the refractive index of skin.
