Abstract
A laser diode includes a laser diode emitting light due to an electrical signal; a wavelength conversion plate for shifting the wavelength of the light emitted from the laser diode; a reflecting part for reflecting the light emitted from the laser diode towards the wavelength conversion plate; and a projecting part for emitting, in the forward direction, the light shifted by the wavelength conversion plate. The laser diode can provide a high-power but small-sized laser light source device, and a narrow emission angle can be achieved using the laser diode.
