ABSTRACT:
A method and apparatus for maintaining a controlled precise energy output level for a laser diode, particularly useful in a precision scanning environment, provide for a thermal stabilization current to be added to the normal bias exposure current of the diode The thermal stabilization current is modeled to account for the temperature variation of the laser diode junction which affects the light energy output as a function of current. The addition of the thermal stabilization current provides a substantially flat and constant, precise output energy from the laser diode during its "on" time as a function of an input exposure value.
