  • Patent number: 10935428
    Abstract: A spectrum measurement apparatus includes a signal generation unit, a detector, an AD converter, and an operation unit. An external cavity laser light source includes a quantum cascade laser and a diffraction grating. The signal generation unit outputs a wavelength sweep signal repeatedly giving an instruction for sweep of a resonant wavelength selected by the diffraction grating and a pumping instruction signal repeatedly giving an instruction for on/off of pumping of the quantum cascade laser in each period of wavelength sweep based on the instruction of the wavelength sweep signal. The operation unit inputs a digital value output from the AD converter, obtains an oscillation spectrum in each period of the wavelength sweep, and integrates the oscillation spectra obtained with changing the phase of the pumping instruction signal for each period of the wavelength sweep.
