FIELD: personal demand items.
SUBSTANCE: shaving head for hair shaving device contains an optical system with the possibility of directing the laser beam through the shaving zone in the shaving head. The laser beam includes a fast and slow axes. The optical system contains a focusing lens. It forms the first focus of the laser beam in the shaving zone. The focusing element refocuses the laser beam to form the second focus of the laser beam in the shaving zone. In another embodiment, the focusing lens forms the focal length of the laser beam in the shaving zone along its fast axis, which is greater than the focal length of the laser beam in the shaving zone along its slow axis.
EFFECT: increased effective laser shaving area in the shaving zone.
