LASER SHAVING
A device configured to cut hair using laser light includes a handle portion and a shaving portion. The handle portion includes a battery and a laser light source. The laser light source is coupled to and configured to receive power from the battery. The laser light source is also configured to generate laser light having a wavelength selected to target a predetermined chromophore to effectively cut a hair shaft. The shaving portion includes a support and a single fiber optic supported by the support. The fiber optic has a proximal end, a distal end, an outer wall, and a cutting region positioned towards the distal end and extending along a portion of the side wall. The fiber optic is positioned to receive the laser light from the laser light source at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit the light out of the cutting region and toward hair when the cutting region is brought in contact with the hair.
1 . A device configured to cut hair using laser light, the device comprising:
a shaving portion configured to be coupled to a handle portion, the shaving portion comprising:
a support;
a fiber optic supported by the support, the fiber optic having a proximal end, a distal end, an outer side wall, and a cutting region positioned towards the distal end and extending along a portion of the outer side wall; and
a coating positioned on at least a portion of the fiber optic;
wherein the shaving portion is configured to provide laser light having a wavelength selected to target a chromophore to cut a hair shaft, and
wherein the fiber optic is positioned to receive the laser light at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit at least a portion of the laser light out of the cutting region and toward hair when the cutting region is brought in contact with the hair.
