The mechanism of filamentation formed by femtosecond pulse laser beam propagating in atmosphere is investigated.

分析了飞秒激在大气中传输的形成机理。

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.
