    Abstract: A handheld household laser hair removal instrument, which belongs to the field of laser hair removal, and comprises a hair removal instrument body, and a laser (1), an optical waveguide (2), a heat dissipation unit, a cooling unit and a controller that are disposed on the hair removal instrument body. The laser (1) comprises a substrate (11) and a plurality of laser chips (12) that are disposed on the substrate (11), and a laser beam emitted by the laser chips (12) is perpendicular to the substrate (11). The optical waveguide (2) is used for shaping the laser beam, and a treatment window (21) is formed on an end surface of the optical waveguide (2). The heat dissipation unit is used for dissipating heat, and the cooling unit is used for cooling the optical waveguide (2). The light exit direction of the laser beam is perpendicular to the substrate (11) which achieves the integration of a high-density two-dimensional area array, achieving the output of different powers or different wavelengths. The heat dissipation unit directly abuts against the substrate (11) for heat dissipation, and the heat dissipation unit has a simple structure. In addition, the optical waveguide (2) is directly cooled by using the cooling unit, and the end surface of the optical waveguide (2) is used as a treatment window (21) to cool the skin in a treatment region, so that the feeling of pain during hair removal may be relieved, and hair removal efficiency may be improved.
