Abstract
An object of the present technique is to improve safety in a semiconductor laser driving apparatus that diffuses laser light by a diffusion plate. A substrate incorporates a laser driver, and a semiconductor laser is mounted on one surface of the substrate. Connection wiring electrically connects the laser driver and the semiconductor laser to each other with a wiring inductance of 0.5 nanohenries or less. A diffusion plate diffuses laser light irradiated by the semiconductor laser. A transparent conductive film is formed on a predetermined surface of the diffusion plate. In addition, the laser driver drives the semiconductor laser to irradiate the laser light on the basis of an electric characteristic value of the conductive film.
