<p>PROBLEM TO BE SOLVED: To provide a laser material processing nozzle provided with an aperture capable of removing miscellaneous light components in higher order components and avoiding the influence of derivative diffracted waves. SOLUTION: In the laser material processing nozzle, such as a laser processor, a nozzle tip 2 is fitted to the tip of a nozzle holder 1 and, a circular cooling part 3 is internally provided in the fitting part of the nozzle holder 1 and the nozzle tip 2. One or more apertures 4 provided with holes 5, 6 having a restricting function for removing miscellaneous light components generating diffracted waves of a laser beam LB are fitted to the nozzle.</p> |
