Claims

[Scope of utility model registration request]

A plurality of optical energy splitters for branching and extracting part of the optical energy output from the plurality of laser oscillators, a plurality of switches for passing and blocking the branched laser beams, and the opening/closing device. An optical coupler that combines multiple laser beams that have passed through the device onto the same optical axis, and an output laser beam that shifts the waveform of the laser beam by a predetermined amount using the output laser beam from the optical coupler as input. a wavelength shifter for inputting the wavelength-shifted laser beam, a wavelength scanner for continuously scanning and changing the wavelength of the laser beam within a predetermined range and outputting the same; a wavelength detector for detecting that the wavelength of the laser beam matches a predetermined value; and a wavelength detector for branching a part of the optical energy from the optical coupler to bypass the wavelength shifter and the wavelength scanner. The laser oscillator uses an optical system for direct input to the wavelength detector, the amount of optical wavelength shift in the wavelength shifter, the amount of wavelength scanning in the wavelength scanner, and the output from the wavelength detector. 1. A wavelength adjustment device for multiplexed laser light, comprising an arithmetic controller that determines the amount of adjustment of the oscillation wavelength of the laser beam and transmits an adjustment signal to a plurality of laser oscillators.
