ABSTRACT:
A laser light source device includes a light source section, and a drive current controller. The light source section includes a first and second fundamental light source component, and a wavelength conversion component. The first and second fundamental light source components emit first and second fundamental wave lights according to supplied drive currents, respectively. The drive current controller controls the drive currents supplied to the fundamental light source components. The wavelength conversion component performs wavelength conversion of the first and second fundamental wave lights to produce first and second converted lights. The first and second fundamental light source components emit the fundamental wave lights such that the first and second converted lights have substantially same color, and the first and second converted lights have no mutually overlapping timing at which light intensities of the converted lights reach their peak.
