Abstract
Laser processing device (100) includes laser oscillator (10) that generates laser light beam (LB), optical fiber (30) that transmits laser light beam (LB), laser head (40) that emits laser light beam (LB) to workpiece (W), and chiller (50) that passes and circulates cooling water through laser oscillator (10) to cool laser oscillator (10). Laser oscillator (10) includes: a plurality of laser diodes; and a base having a cooling water channel therein and having the laser diodes mounted on a surface thereof. Laser processing device (100) is configured to change the incident angle of laser light beam (LB) entering optical fiber (30) by changing the water pressure of the cooling water flowing through the cooling water channel.
Claims7
A laser processing device comprising:
- a laser oscillator that generates a laser light beam;
- an optical fiber that transmits the laser light beam;
- a laser head that receives the laser light beam transmitted through the optical fiber and emits the laser light beam to a workpiece;
- and
- a chiller that allows cooling water to flow through the laser oscillator to cool the laser oscillator,
- wherein
- the laser oscillator includes
- one or more laser diodes, and
- a base that includes a cooling water channel inside and has the one or more laser diodes mounted on a surface of the base, and
- the laser processing device is configured to change an incident angle of the laser light beam incident on the optical fiber by changing a water pressure of the cooling water circulating through the cooling water channel.
