世界上激光器问世是在 1 960年 6月 ,中国第一台激光器出来是在 1 961年 9月 ,相差十五、六个月。实际上激光器的出现经过很长的酝酿时期。今天追溯起来 ,激光的起源在理论上归功于 1 91 6年爱因斯坦提出的感应辐射概念。《关于辐射的量子理论》作为里程碑的是 50年代出现了微?
The laser came out in June 1960 in the world. The first laser in China came out in September 1961, a difference of fifteen or six months. In fact the emergence of the laser after a long period of brewing. Today, retrospectively, the origin of the laser is theoretically attributed to the concept of induced radiation proposed by Albert Einstein in 1961. As a milestone in the “Quantum Theory of Radiation”, what happened in the 1950s?
