超快激光和电光技术迅速发展超快源的发展受化学和物理学各种研究应用的推动。超快光脉冲大体可定义为持续时间在千万亿分之一秒（１０－１５Ｓ）到万亿分之一秒（１０－１２Ｓ）间的脉冲。科学家以超快光源探测反应光谱学和半导体动力学，监视光化学和燃烧过程，以及研究... The rapid development of ultrafast laser and electro-optic technology The development of ultrafast source is driven by various research applications in chemistry and physics. An ultra-fast light pulse can be broadly defined as a pulse lasting in the tens of pettillionths of a second (10-15 S) to one trillionth of a second (10-12 S). Scientists probe reaction spectroscopy and semiconductor dynamics with ultrafast light sources, monitor photochemical and combustion processes, and ...
