light amplification meaning in English

光放大

In chapter 5 , we make numerical calculation , then analyze the properties of the population distribution , the gain , the coherence term and population difference , and validate the transient light amplification mechanism of this system
第五章我们根据数值计算结果分析了粒子数分布、增益、相干项和粒子数差的瞬态演化过程，验证了系统产生增益的机制。
In 1958 , professor townes and dr . a . l . schawlow showed theoretically that masers could be made to operate in the optical and infrared region and this work resulted in their joint paper on optical and infrared masers , or lasers ( light amplification by stimulated emission of radiation )
一九五八年，汤斯教授和邵卢博士（ arthurl . schawlow ）在理论上证明maser在可见光和红外线的范围亦可运作，并共同发表关于可见光和红外线激射放大器，亦即laser （ lightamplificationbysimulatedemissionofradiation ）的论文。
