Abstract:
A system for generating a shaped optical pulse is disclosed. The system includes a master oscillator for generating an initial optical pulse, which is then directed to a semiconductor optical amplifier to amplify a portion of the initial optical pulse. The amplified pulse is reflected from a fiber Bragg grating to spectrally clean the amplified pulse and the reflected portion is returned back through the semiconductor optical amplifier. The semiconductor optical amplifier is activated a second time to amplify the reflected portion of the pulse. The time delay between the two activations of the semiconductor optical amplifier is selected to generate an output pulse with desired duration and/or amplitude profile over time.
