ABSTRACT:
A semi-conductor laser device constant power output controller including a power input, a laser diode device consisted of a laser diode and a photoelectric diode, a current driver consisted of a first transistor and a second transistor, and an output control consisted of a zener diode and a variable resistor, whereby the electric current to the laser diode is controlled by the second transistor; the electric current to the second transistor is controlled by the first transistor; the photoelectric diode detects the laser beam of the laser diode for feedback reference; the zener diode and the variable resistor control the output power by means of controlling the electric current to the laser diode.
