| Zusammenfassung: | A laser emitting device has a constant current source, a single charging capacitor, and one or more laser emitters. The constant current source supplies a charging current to the single charging capacitor to charge the single charging capacitor. Each of the laser emitter has a laser diode and a drive circuit. Each laser diode emits laser light in response to a power supplied from the single charging capacitor. A charging current to be supplied to the single charging capacitor is less than a threshold current of the laser diode in each of the laser emitters. |
