Abstract
A dual mode electronic amplifier controller is disclosed. The amplifier includes a first amplifier electronically connectable to an optical input signal and a second amplifier electronically connectable to an optical output signal. The first amplifier has a first output and the second amplifier has a second output. The amplifier controller further includes a microprocessor electronically connected to the first and second outputs. The microprocessor is adapted to operate in one of a first mode wherein the microprocessor compares functions of the first and second outputs and generates a first microprocessor output, and a second mode wherein the microprocessor compares the second output to a predetermined value and generates a second microprocessor output, such that, in either the first or second modes, each of the first and second microprocessor outputs is adapted to adjust electrical current to a laser.
