摘要

A plurality of surface emitting lasers are formed on the single surface emitting laser element. The plurality of surface emitting lasers have respective emission wavelengths selected from wavelengths satisfying condition of:; 0λ₁−λ_s≤5.36×10⁻⁵λ_c²−×5.83×10⁻²λ_c+32.4where a first emission wavelength is λ₁ [nm], a second emission wavelength shorter than the first emission wavelength is λ_s [nm], and a middle wavelength between the first emission wavelength and the second emission wavelength is λ_c [nm]. At least one of the plurality of surface emitting lasers has an emission wavelength different from an emission wavelength of another surface emitting laser.
