  • Laser beam combining apparatus, and combined stepped reflector and filling rate calculation method thereof
    Patent number: 12276814
    Abstract: A laser beam combining apparatus, and a combined stepped reflector and a filling rate calculation method thereof are disclosed. The laser beam combining apparatus includes a two-dimensional light-emitting array and the combined stepped reflector used to reflect a plurality of laser beams emitted by the two-dimensional light-emitting array. The combined stepped reflector is composed of a plurality of reflective mirrors that have the same length but sequentially increasing widths and that are stacked in succession, where the distance between centers of the laser beams reflected by the combined stepped reflector is smaller than the distance between centers of the laser beams prior to the incidence, thus increasing the filling rate of the laser beams emitted by the two-dimensional light-emitting array. A method for calculating the filling rate of the laser beam combining apparatus is also provided.
