ABSTRACT:
An apparatus for controlling a laser diode (135) includes a photodiode (136) which monitors an output light (P.sub.pump) of the laser diode (135) and a control signal generator (132) which generates a control signal in response to an output of the photodiode (136). The apparatus also includes a driver circuit (134) which drives the laser diode (135) in response to the control signal so that the laser diode (135) generates a constant power of light.
