In this article, the space coherence of XeCl laser is measured with various cavity Q using Young's experiment. It shows than the amplified spontaneous emission ( ASE) is the important factor which affects the space coherence of XeCl lasers. 本文采用杨氏实验的方法,在不同的谐振腔Q值条件下测量了XeCl激光的空间相干性,认为放大自发辐射(ASE)是影响XeCl激光空间相干性的重要因素。
With the combination of the chromatographic zone sharping effect and field amplified sample stacking effect, the sensitivity of caffeine was improved by a factor of 24,000. 利用色谱区带压缩效应和场放大效应,对碱性化合物***的检测灵敏度提高了24000倍。
We assume that two individuals have higher productivity if their types are different, that is their payoff matrix are amplified by a multiplicative factor; while the payoff matrix remains unchanged, if their are of a same type. 我们假定当两个个体类型不同时他们具有更高的工作效率,即将收益矩阵用一个因子放大;当两者类型相同时,收益矩阵不变。
In two-unit cascaded FDL system, amplified spontaneous emission noise introduced in first stage is a major factor for output SNR deterioration. 两级延时线级联系统中,第一级延时线中SOA引入的ASE噪声是输出信噪比恶化的主要因素。
