Abstract
A laser processing head comprises nozzle-holding means () for holding a nozzle in which a nozzle hole () is formed; condensing optical system-holding means () for holding a condensing optical system (), the condensing optical system-holding means being slidably arranged in the nozzle-holding means while maintaining sealing, moving means () for slide-moving the nozzle-holding means and the condensing optical system-holding means relative to each other; gas-feeding means () for feeding a gas into a laser processing head chamber () formed between the condensing optical system of the condensing optical system-holding means and the nozzle hole of the nozzle-holding means; passages () formed in the nozzle-holding means to communicate the laser processing head chamber with the exterior of the nozzle-holding means; slide members () that slide in the passages while maintaining sealing; and coupling means () for coupling the slide members to the condensing optical system-holding means. Therefore, the condensing optical system-holding means or the nozzle-holding means can be moved with a small force without providing an annular gas sub-chamber.
