摘要：
There is provided a hair cutting device for cutting hair on a body of a subject, the hair cutting device comprising a source for generating light at one or more specific wavelengths corresponding to wavelengths absorbed by one or more chromophores in or on hair； a cutting element that comprises an optical waveguide that is coupled at a first end to the source to receive light, wherein a portion of a sidewall of the optical waveguide forms a cutting face for contacting hair； a sensor for measuring a force acting on the cutting element； and a control unit that is coupled to the source and the sensor, wherein the control unit is configured to control the power of the light generated by the source based on the measured force, and wherein the power of the light is controlled to a first non-zero level if the measured force is below a first threshold, and controlled to a second non-zero level if the measured force is above a second threshold, wherein the first non-zero level is less than the second non-zero level and the first threshold is equal to or less than the second threshold.
