摘要
通过一台NdYAG激光器抽运两台脉冲染料激光器,产生589 nm和770 nm两种可调谐波长激光,分别激发钠层和钾层原子的共振荧光,再通过双光纤焦面分光接收,实现了利用一台激光雷达同时探测高空钠层和钾层,从而为更经济、更有效地开展高空钠层和钾层比较性探测研究提供了一种新的手段。
Abstract
A NdYAG laser emits two 532-nm laser beams to pump two pulsed dye lasers, respectively. Then one dye laser will emit a 589-nm laser beam for Na layer detection, while the 770-nm laser beam for K layer detection is obtained from the other dye laser. The scattering echoes of these two laser beams are collected with the same telescope, and transmitted by two fibers set in the telescope′s focal plane, respectively. Therefore, we have realized the simultaneous observation of Na layer and K layer by using only one lidar system and have gotten a new and economic detection tool for upper atmospheric Na layer and K layer observation.
