An attosecond precision and femtosecond range timing jitter measurement and control technique is proposed. It is based on the modulation of the combined pulse induced by relative time delay of individual pulses. The core of this timing jitter detection method is the integrated technique of optical cross correlation and electrical energy interferometry. To illustrate this technique, a proof-of-principle experiment is demonstrated based on two 237 fs pulses. The peak-to-valley timing jitter of the two pulses to be combined is less than 700 as in 1 h and the average efficiency of coherent beam combining could reach to 91.6%.

采用稳态发光光谱、瞬态发光动力学测量等手段，对两种钌配合物［Ru(bpy)3］(ClO4)2和［Ru(bpy)2HPIP］(ClO4)2的发光性质进行了研究。稳态发光光谱表明［Ru(bpy)2HPIP］(ClO4)2发光明显偏弱；皮秒瞬态发光动力学测量显示［Ru(bpy)2HPIP］(ClO4)2的激发态弛豫过程存在皮秒量级的快过程，可能与由于HPIP配体的存在,使电荷转移态和溶剂分子产生氢键作用有关。纳秒瞬态发光动力学测量的结果则显示了所有样品共同具有的瞬态发光衰减过程，实验结果符合能隙定律，推断其来自没有和溶剂分子形成氢键结合的配合物的激发态弛豫过程。
