Laser processing head and laser processing system

A laser processing head that combines a first laser beam and a second laser beam different from each other to irradiate a workpiece with the combined laser beams, the laser processing head comprising:

• a bend mirror that bends the second laser beam in a direction intersecting the first laser beam;
• a dichroic mirror that transmits most of the first laser beam toward the workpiece and reflects most of the second laser beam toward the workpiece;
• a workpiece-side condensing lens that condenses each of the first laser beam and the second laser beam to irradiate the workpiece with the condensed laser beams between the dichroic mirror and the workpiece;
• a photodetector that receives each of a rest of the first laser beam reflected by the dichroic mirror and a rest of the second laser beam transmitted through the dichroic mirror;
• a detection-side condensing lens that condenses each of the first laser beam and the second laser beam to irradiate the photodetector with the condensed laser beam between the dichroic mirror and the photodetector;
• and
• an adjuster that adjusts a workpiece-side condensing state that is a condensing state of at least one of the first laser beam and the second laser beam on an image plane on a workpiece side,
• wherein
• the photodetector detects a detection-side condensing state corresponding to the workpiece-side condensing state, the detection-side condensing state being a condensing state of at least one of the first laser beam and the second laser beam on an image plane on a photodetector side, and
• the workpiece-side condensing state is adjusted by the adjuster based on the detection-side condensing state.
