In 1986, General Zhang Aiping named the high-intensity pulsed laser experimental device with peak power exceeding 112 watts, which made China a country with similar equipment after the United States, the Soviet Union, France and Japan. After exploring a variety of lasers, high energy laser weapon team led by Wang Zhijiang finally chose solid-state lasers as the attack direction, but the technical conditions at home and abroad were not mature at that time, so the plan had to be shelved temporarily in 197. There are many reasons for the suspension of the plan, mainly because intelligence at that time showed that foreign countries made frequent progress in this field, which stimulated the military high-level officials and mistakenly thought that success was close at hand. Mao Zedong even issued a written military order that must be developed. In the Cultural Revolution, when politics was overwhelming, there was a shortage of manpower and material resources, a lack of strict scientific argumentation and analysis, and no guarantee of resources, technical reserves and industrial base. The solid-state laser was hastily positioned as the main direction, which eventually made the plan difficult to produce. In fact, many theoretical studies at home and abroad were still in the primitive stage, so they were too optimistic about the development of laser cannons, and the results were not surprising when the technical conditions and environment were not mature. After the plan was put off, the company transferred its resources to the research of mature and practical laser devices, so that the quality of solid-state high-power laser and its important component laser crystal reached the international advanced level. Although the laser weapons program was suspended, some people were still left to carry out basic research so that they could make a comeback in the future.
