PULSE LASER OUTPUT STABLIIZATION APPARATUS AND METHOD OF THE SAME

摘要

The present invention is to provide a pulse laser output device and method thereof. The pulse laser output device comprises the first optical path and the output light of the pulse laser received, the directional coupler branching off to the second optical path of the optical detector which outputs the current according to the light-intensity of the light branched to the first optical path and received the current-to-voltage converter, it outputs and converts the output current of the optical detector into the voltage of the function generator providing the output proportional of the output signal to the current-to-voltage converter with the predetermined frequency, and the time delaying unit, which is located opposed to the second optical path, provides the predetermined time delay for the feedback control, and the anastomotic variable modulator in which the optical signal provided from the output signal and time delaying unit of the function generator are received to the input and modulates the optical signal provided from the time delaying unit according to the size of the output signal of the function generator are outputted.
