Abstract
To obtain pulsed light signal used as pulsed pump light for optical fiber sensing and communication systems, a design scheme of generating pulsed light based on continuous laser and Field Programmable Gate Array (FPGA) is proposed in this paper. The pulsed light signals with minimum pulse width of 10 ns were obtained in the experiment, the pulse widths of the pulsed light signals could be regulated with the smallest increment of 5 ns, while the deviations of the pulse widths were less than 0.8 ns between the measurements and the expected values. The repetition frequency could also be adjusted from 0.05 Hz to 100 MHz. Not only is the pulsed light signal stable and reliable, but the complexity of the system is also reduced by using the design method in this paper.
