1. A hair cutting device, configured to cut a hair near skin of a human body part or animal body part, comprising:
an optical source configured to generate optical radiation for cutting the hair; and an optical blade, wherein the optical blade comprises a blade body configured to guide the optical radiation; a tapered end having a curved wall and an exit window with a flat shape configured to allow the optical radiation to exit the optical blade; and a straight wall meeting the curved wall of the tapered end and configured to contact the hair, wherein the tapered end comprises a reflector configured to redirect the optical radiation before exiting the optical blade through the exit window, and wherein the optical source and the optical blade are arranged in such a way that the optical radiation from the optical source which is coupled into the blade body is directed to the tapered end and coupled out of the optical blade after reflection at the reflector.
