The diffraction angle of the return light 103b/-2 is larger than the diffraction angle of the return light 1 〇3 a — - 2 (Using the principle that the longer the wavelength, the larger the diffraction angle is in the diffraction grating.) Moreover, by using the difference in the diffraction angle, the laser light is made to be 1 0 3 a > 1 0 3 before being diffracted. The distance between the individual optical axes of b > is D.
