China Mid-course Interception of ICBM Enabled by Scientists’ DLC FilmPosted: July 29, 2015
China’s Science and Technology Daily and ifeng.com both carry true story of China’s top laser scientist Cheng Yong’s marvelous achievements.
What Cheng Yong and his team do is unique in entire PLA. They 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, coherent combination of mutual injection, etc.
Cheng is brave in tackling the problems that even US experts find difficult. He made world first adjust-free solid laser.
That achievement has made Cheng even braver. When he learnt in 2000 that China’s infrared window, the eye of China’s large weapon, was not hard enough to resist injury or chemically stable enough to resist erosion, especially became blind under hypersonic speed, he spent 4 years in developing DLC film prepared by laser deposition.
At first, the film fails hypersonic test. He made unremitting efforts to improve the technology and finally mastered the key technology for such film in 6 years.
Ifeng.com says that the film was used in China’s new ICBM defense missile to increase its speed by 30%. In 2011, the missile successful passed a test to intercept an ICBM in mid course. Foreign media call the new missile Hongqi-19.
