ABSTRACT:
A driving circuit for a laser diode has an exciting circuit for intermittently exciting the laser diode. A photodiode is provided for detecting the beam power emitted from the laser diode, and a resistor is connected to the photodiode in series. Voltage across the resistor is stored in a capacitor of a charging circuit. The stored voltage is applied to a constant current circuit to control a current supplied to the laser diode to stabilize beam power of the laser diode.
