We will develop a novel high power source of 589nm coherent (laser) light to be used to create a laser guide star by exciting sodium atoms in the earth's upper atmosphere (the mesosphere). This is needed to determine the distortion caused by the atmosphere on an optical beam propagating through it and generate the information needed to correct those distortions using an adaptive optics telescope. This project focuses on the development of a novel high power 589nm source based on a synchronously pumped optical parametric oscillator.

我们将开发一种新型的高功率589 nm相干（激光）光源，用于通过激发地球上层大气（中间层）中的钠原子来创建激光引导星星。这需要确定大气对通过大气传播的光束造成的失真，并产生使用自适应光学望远镜校正这些失真所需的信息。本项目主要研究基于同步泵浦光参量振荡器的新型高功率589nm光源。
