The mechanism of filamentation formed by femtosecond pulse laser beam propagating in atmosphere is investigated. 分析了飞秒激光脉冲在大气中传输时光丝的形成机理。
This article discusses the femto-chemistry, because it involves femtosecond laser pulses, and its research or monitor into chemical processes of transition state and intermediate. 讨论由飞秒激光脉冲所构成的飞秒化学,及其对化学反应过渡状态或中间体的研究和检测。
A femtosecond is the SI unit of time equal to 10 or /1,000,000,000,000,000 of a second. That is one quadrillionth, or one millionth of one billionth, of a second. For context, a femtosecond is to a second as a second is to about 31.71 million years; a ray of light travels approximately 0.3 µm (micrometers) in 1 femtosecond, a distance comparable to the diameter of a virus.
