Abstract:
1. A device for shortening hairs comprising: a laser source for generating a laser beam; an optical system for focusing the laser beam into a focal spot; and a laser beam manipulator for positioning the focal spot in a target position, characterized in that a dimension of the focal spot and a power and wavelength of the generated laser beam are such that, in the focal spot, the laser beam provides laser induced optical breakdown phenomenon as to the hair tissue so as to damage the hair tissue via a mechanical effect; wherein the device further comprises: an image sensor for detecting an image of at least a portion of a skin with hairs to be shortened, an image recognizing system for determining a position and/or orientation of the hairs relative to the skin, and a control system for determining the target position of the focal spot as a function of said position and/or orientation of the hairs, wherein, during operation, the control system adjusts the laser beam manipulator into a position corresponding to the target position of the focal spot and, subsequently, activates the laser source.
