Laser Processing Apparatus

A laser processing apparatus includes a processing nozzle. The processing nozzle includes an upper wall having a laser beam passage port defined therein, a lower wall that is connected to a lower portion of a part of the upper wall and that includes a debris capturing chamber defined therein, a suction port defined between another part of the upper wall and the lower wall, a first air ejection port defined in the lower wall, for ejecting air across the debris capturing chamber toward the suction port in a predetermined direction perpendicular to an optical path of a laser beam, and a second air ejection port defined in the lower wall below the first air ejection port, for ejecting air in the predetermined direction. A flow rate of air ejected from the second air ejection port is smaller than a flow rate of air ejected from the first air ejection port.
