Abstract: A light source unit includes: a sealed semiconductor laser package including a laser diode that includes an emitter region from which laser light is emitted, the emitter region located at a surface of the laser diode, and a window member configured to transmit the laser light; a first lens structure configured to receive the laser light transmitted through the window member and create an image of the emitter region on an image plane; and a second lens structure configured to convert the laser light having passed through the image plane into a collimated or converged beam, and to emit the collimated or converged beam.
