摘要：
The present application relates to a cutting head for a device for cutting hair. The cutting head has a laser generator (2) and an optical system (3). The optical system is configured to focus a laser beam (4) generated by the laser generator and direct the laser beam along an optical axis (16) across a cutting zone (8) in the cutting head. The laser generator and optical system are configured such that, in a focus spot (15) of the laser beam, a dimension of the focus spot, a power density of the laser beam and the numerical aperture of the laser beam are such that, when a hair is received in the cutting zone, the power output of the laser generator is minimised whilst ensuring that, for a predetermined exposure time, the hair received in the cutting zone is cut by optical absorption. The present application also relates to a device for cutting hair and a method of controlling a cutting head for a device for cutting hair.
