摘要：
A laser device includes a resonator having a gain region, a first wavelength selection portion having a periodical peak in wavelength characteristics and a second wavelength selection portion having a periodical peak in wavelength characteristics in a wavelength range smaller than a variable range of an oscillation wavelength at a period different from the first wavelength selection portion, the oscillation wavelength selected with a single direction changing of a refractive index of the second wavelength selection portion changing in a single direction; a storing portion storing a setting value of a refractive index of the second wavelength selection portion for selecting an oscillation wavelength according to an oscillation wavelength to be attained within an extent from a maximum value to a minimum value of the refractive index over the plurality of the ranges; and a controller giving the setting value to the resonator.
