Abstract

집관렌즈에 의해 레이저비임이 조사된 피가공부로부터 비산된 스패터 (SPATTER)가 집광렌즈와 피가공부의 사이에 배열된 보호유리에 부착되는 현상을 방지한다.
피가공부(30)에 집광된 레이저비임을 조사하는 집광렌즈(20)와 피가공부(30)의 집광렌즈(20)에 대한 상대이동방향으로 향해서 뚫린 분사구(23b)로 부터 피가공부(30)에 불활성가스를 공급하는 가스송출장치(23)과 피가공부(30)에 조사된 레이저비임의 광축에 대해서 경사진 방향으로 향해서 뚫린 분사구(22b)로부터 피가공부(30)과 집광렌즈(20)과의 사이에 공기커텐을 형성하는 공기를 분사하는 공기송출장치(22)등을 갖춘다.
