Abstract: Laser processing head 10 includes housing 11 and a plurality of optical components. Housing 11 is provided with partition wall 11a, first and second light entrance ports 12a, 12b through which first and second laser beams A, B respectively enter, and light irradiation port 13. Laser processing head 10 includes first and second photodetectors 91b, 92a provided around first and second light entrance ports 12a, 12b, respectively. First photodetector 91b is disposed opposite to second photodetector 92a across partition wall 11a. First photodetector 91b receives light in the second wavelength band including the wavelength of second laser beam B, and second photodetector 92a receives light in the first wavelength band including the wavelength of first laser beam A.
