The following is based on translations of reports on Chinese news sites:
The report says that Cheng Yong and his team have been making breakthroughs in strategic technology vital to the development of photoelectric equipment such as adjust-free laser, DLC film prepared by laser deposition and coherent combination of mutual injection, etc.
Cheng has tackled problems that even US experts find difficult, including making the world’s first adjustment-free solid laser.
In 2000, Cheng found that China’s infrared window, the eye of China’s large weapon for interception, was not hard enough to resist injury or chemically stable enough to resist erosion, and it became “blind” under hypersonic speed.
To remedy this, he spent four years developing DLC film prepared by laser deposition.
The film was used in China’s new ICBM defence missile to increase its speed by 30%. In 2011, the missile successfully passed a test to intercept an ICBM in mid course.
Foreign media call the new missile Hongqi-19.
