ABSTRACT:
A wavelength determining apparatus is disclosed. The wavelength determining apparatus includes a reflection block, a light detection block, and a determination block. The reflection block receives at least part of a laser light beam emitted from an external cavity type semiconductor laser and emits a reflected light beam that has a distribution of light intensities of fringes. The light detection block detects the intensity of the light beam reflected from the reflection block in two or more light reception positions. The determination block obtains a difference value of detection signals in the two or more light reception positions and determines the wavelength of the laser light beam on the basis of the difference value. The two or more light reception positions are arranged in the direction of which the fringes take place.
