PROBLEM TO BE SOLVED: To reduce the coherence of laser light which a laser light source having a wavelength-converting element emits. SOLUTION: A laser light source device 100a is provided with a first laser array light source 102a which emits a light W14a of a first wavelength; and a second laser array light source 104, which emits a light W24 of a second wavelength different from the first wavelength. The first laser array light source 102a has a first fundamental wave laser array 110a, which generates a first fundamental wave W11a of first original oscillation wavelength and a first wavelength-converting element 130a which wavelength-converts the first fundamental wave W11a, to generate the light W14a of the first wavelength. The second laser array light source 104 has a second fundamental wave laser array 110, which generates a second fundamental wave W21 of a second original oscillation wavelength, different from the first original oscillation wavelength and a second wavelength-converting element 130, which wavelength-converts the second fundamental wave W21, to generate the light W24 of second wavelength.
