<p>PROBLEM TO BE SOLVED: To provide a laser light source device that can reduce speckle noise sufficiently.SOLUTION: A laser light source device 1 comprises a plurality of light source parts 2, 2 for emitting laser lights with wavelengths. In first and second light source parts 2a, 2b out of the plurality of light source parts 2, 2, a ratio of a product of a spectral sensitivity of a wavelength of a laser light emitted from the first light source part 2a and an output of the laser light, to a product of a spectral sensitivity of a wavelength of a laser light emitted from the second light source part 2b and an output of the laser light is 0.67 to 1.50.</p> |
