Zusammenfassung: | To reduce the wiring inductance between a semiconductor laser and a laser driver in a semiconductor laser driving apparatus.A substrate incorporates a laser driver. A semiconductor laser is mounted on one surface of the substrate of a semiconductor laser driving apparatus to emit irradiation light from an irradiation surface. 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 temperature sensor measures a temperature relating to the semiconductor laser. A memory stores control data from the laser driver to the semiconductor laser in a manner corresponding to the temperature. |
