英文摘要 | A laser driving method is adapted for driving a plurality of laser emitting devices. A first current to be supplied to each of the plurality of laser emitting devices is always generated. A plurality of second currents controlled according to a control signal supplied from the outside are generated when necessary. The plurality of second currents are supplied to the respective laser emitting devices under supply of the respective first currents, thereby making the laser emitting devices emit respective laser beams. The plurality of laser emitting devices are caused to emit the laser beams in time division at predetermined timing to detect each of emitted light amounts by one laser monitor. Adjustment is made to at least one of the first current and the second current supplied to each of the laser emitting devices according to a plurality of detected light amounts detected. Supply of the current to the laser emitting devices not driven is stopped when the plurality of laser emitting devices are adjusted in light amount in time division. |
