Theoretical research on obtaining of picoseconds dilated pulses with a framing imaged converter tube

摘要： Variations in the temporal resolution of a pulse-dilation framing imaged converter tube (FICT) were studied. The relation between temporal resolution and dilated pulse was analyzed. The computational methods for describing pulse gradient and time-varying amplitude were derived. It explores the possibility of obtain picoseconds ultrafast pulses and the others potential application FICT from a theoretical perspective. The results show that it is higher precision to achieve the shape and amplitude of an ultrafast dilated pulse using a FICT. The relative standard deviation (RSD) range of ten thousand sample data was 5.8% when the time step is 50 ps, and the RSD is reduced to 1.9% as the time step is shortened to 10 ps. We expect that our results will expand the others potential applications of FICTs and provide that a theoretical basis for further optimizing relevant external systems of FICT.
