Semiconductor laser driving apparatus, electronic equipment, and manufacturing method of semiconductor laser driving apparatus

Electronic equipment comprising:

• a substrate incorporating a laser driver;
• a semiconductor laser mounted on one surface of the substrate to emit irradiation light from an irradiation surface;
• a connection wiring that 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 for measuring a temperature relating to the semiconductor laser;
• and
• a memory for storing control data from the laser driver to the semiconductor laser in a manner corresponding to the temperature.
