lase

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

化学激光器是以释能化学应提供能源, 并且以化学应产生粒子数。

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