Title: LASER BEAM SOURCE DEVICE
Abstract:
The laser beam source device (1) is provided with a plurality of light source units (2, 2) emitting laser beams of different wavelengths. In a first and a second light source units (2a, 2b) among the plurality of light source units (2, 2), the ratio of the product of the spectral response at the wavelength of a laser beam emitted by the first light source unit (2a) and the output of the laser beam, to the product of the spectral response at the wavelength of a laser beam emitted by the second light source unit (2b) and the output of the laser beam, is 0.67 to 1.50.
