Hou Xun won the individual award, ranking fifth.

In order to further develop China's transient optical technology and promote the study of ultrafast phenomena, he initiated and organized the establishment of the "State Key Laboratory of Transient Optical Technology" and achieved success. 199 1 year, organized an application for the establishment of "femtosecond laser technology and ultrafast process research" and the "Eighth Five-Year Plan" climbing project, and was hired as the chief scientist of the project by the State Science and Technology Commission after approval. The project consists of femtosecond laser technology, ultrafast measurement technology and ultrafast process research, and is jointly undertaken by relevant scientific and technical personnel from six universities. It has been completed very well: 1996 was rated as a class when it was accepted by the state science and technology commission. Since 1997, as one of the conveners of the expert group of the ninth five-year plan pre-selected project "Research on intense laser physics and femtosecond ultrafast process", he has undertaken the organization and research of ultrafast process research, and was hired as A-level when the project was accepted in 200 1.

In addition, Hou Xun successfully developed a four-stage image intensifier coupled with magnetically focused mica in 1970s. Transmission GaAs cathode and field-assisted photocathode have been successfully developed in China. In the early 1980s, a palladium-silver-cesium oxide cathode with high long-wave response, low surface resistance and good stability was invented. China has successfully developed a double proximity focusing image intensifier; A combined infrared cathode made of electron trap material was invented. Invented a new high-efficiency X-ray photocathode and obtained a Chinese and American invention patent; 1990, a microchannel plate X-ray image intensifier with a diameter of 100 mm was successfully developed. At that time, it was leading at home and abroad, patented by China. In order to solve the problem of detecting dark, small, fast and multi-targets in conventional weapon shooting range, he proposed the method of using pulsed laser illumination, interference filter to suppress background and image intensifier to enhance the target image, and successfully developed a new generation of optical measuring equipment for shooting range in China, which won the second prize of National Science and Technology Progress Award 1992. He attached great importance to the transformation of scientific research achievements, and once presided over the design and manufacture of a complete set of image intensifier manufacturing equipment, earning foreign exchange through export 1, 9 1, 000 USD.

Since he was hired as a professor in 2000, he has co-chaired the 985 project "Massive Information Technology" with Professor Wu Hongcai, led the research work on ultra-high density optical storage of information, passive devices for optical communication, low-loss organic optical fiber, and established the "Shaanxi Key Laboratory of Information Photonic Technology".
