摘要	An optical functional amplifying device suitable for use in an optical gate which operates at a very high repetition frequency such as a frequency exceeding 100 GHz. The device has a semiconductor laser amplifier having a gain section and a saturable absorber section, a first optical coupler for coupling an input signal optical pulse train having a wavelength whose value is set near the absorption edge of the saturable absorber section in to the semiconductor laser amplifier, a second optical coupler for coupling a gate optical pulse train having a wavelength shorter than that of the input signal optical pulse train to the semiconductor laser amplifier, and a selector for separating and extracting a signal optical pulse train emitted from the semiconductor laser amplifier from the gate optical pulse train. The repetition frequency of the gate optical pulse train is set to one N-th the basic frequency of the input signal optical pulse train, N being a natural number, to establish timing synchronization between the gate optical pulse train and the input signal optical pulse train.
