Abstract: A light source unit includes a light source which emits a light bundle in one direction; a polarizing unit which is formed to selectively transmit a certain polarized light of a certain wavelength in the light bundle; and a reflection unit which is formed so as to delay the phase of the polarized light so that the polarized light is reflected by the polarizing unit, convert one part of the wavelength of the polarized light, and reflect the polarized light toward the polarizing unit.

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.
