Original Abstract Submitted
A laser processing device includes a first branching unit that branches laser light into first laser light emitted to a first processing point and second laser light emitted to a second processing point, an optical interferometer that emits measurement light having a wavelength different from a wavelength of the laser light, and generates an optical interference signal based on the measurement light, a lens that condenses the laser light and the measurement light, a first mirror that changes incident positions of the laser light and the measurement light on the lens, a second mirror that changes an incident position of the measurement light on the first mirror, a controller that controls an operation of the second mirror, and a measurement processing section that derives a depth of a keyhole based on the optical interference signal.
