Abstract: A process fiber (20) includes a first light transmitter configured to transmit the processing laser beam emitted from a processing laser source (12) of a laser processing system (1); a measuring laser source (14); and a second light transmitter fixed to the first light transmitter along the length of the first light transmitter and configured to transmit the measuring laser beam emitted from the measuring laser source (14). The bending radius of the first light transmitter at a predetermined position is detected based on the measuring laser beam reflected by the second light transmitter.

Abstract: Laser processing head (20) of the present disclosure includes housing (30), transparent protector (40), and temperature sensor (70). Housing (30) includes an optical path of processing laser light (LB). Transparent protector (40) is detachably fixed to housing (30), passes processing laser light (LB), and suppresses dust of work material (W) entering into housing (30). Here, the dust is generated from the work material (W) irradiated with processing laser light (LB). Temperature sensor (70) detects the temperature of transparent protector (40).
