Although laser pumping using electron beam (EB) has high transient power output and easy modulation based on perovskite quantum dot (PQD) film, its lasing emitting direction is the same as the pumped EB's direction. Thus, realizing the conventional direct device structure through the film lasing mechanism is extremely difficult. Therefore, using the random lasing principle, herein, we proposed a corona modulation device structure based on PQDs random laser pumped using an EB. We discussed and stimulated the optimized designed method of the device in terms of parameters of the electronic optical device and the utilization ratio of output power and its modulation extinction ratio, respectively. According to the simulation results, this type of device structure can effectively satisfy the new random lasing mechanism in terms of high-speed and high-power modulation.

To further enhance transient characteristics of space range-gated imaging system and widen its application potential in astronomical and military domains, a self-triggered structure and complex detecting mechanism are proposed in this paper. There being delays restriction among multiple subsystem of rangegated imaging system and the robust performance of multiple optical axis adjusted are firstly discussed and analyzed. Based on these, by researching the work principle and coupling process of microchannel plates in series in image intensifier, taking advantages of the coupling loss electrons to realize self-triggered is studied and its prototype device structure is further proposed too. Then, the space optical transfer theory of new selftriggered component is deduced and its waveguide process is stimulate in the software. Finally, the selftrigger performance and optical transfer effect of cutting edge invention is verified by vacuum test. And the test results basically match with theoretical model and simulation data.
