Chemical laser is characteristically energized by an exoergic chemical reaction which produces the nece ssary population inversion of lasing species.

化光器是以释能化应提供能源, 并且以化应产生粒数转为基础的。

The numerical results show that the lasing threshold of an eigenmode depends on the EGDF, different eigenmode has different value of EGDF.
