摘要
In this paper, a double-pulse laser with a semiconductor optical amplifier (SOA) is proposed. By adjusting the polarization controller, we observe double pulses with repetition frequencies of 10.05 and 12.70 MHz and pulse widths of 33.40 and 30.13 ns, respectively. The laser consists of a SOA asymmetrically placed in a short fiber loop. Its switching time is determined by the off-center position of the SOA within the loop. In the loop, the two pulses, which have the same widths, transmit in the clockwise direction and the counterclockwise direction separately.
