1. A processing device comprising:
a processor configured to execute adjustment processing for adjusting, based on an intensity of a laser beam not passing through a wavelength filter which specifies a wavelength band of the laser beam from a semiconductor laser for a transmission, the intensity of the laser beam, and adjusting, based on the intensity of the laser beam not passing through the wavelength filter and the intensity of the laser beam passing through the wavelength filter, the wavelength of the laser beam; and
a storage configured to store a result of the adjustment processing,
wherein the processor executes the adjustment processing for a plurality of the semiconductor lasers, and
wherein the processor executes, when the adjustment processing for one of the semiconductor lasers is executed and the adjustment of the intensity and the wavelength of the laser beam for the one of the semiconductor lasers reaches a limit, the adjustment processing for one of the other the semiconductor lasers.
