摘要

天文学中越来越多的自适应光学系统使用钠激光导星(LGS)。分析返回荧光的畸变需要高功率激光器。我们在这里展示了两个基于纵向泵浦1厘米长的染料电池的非模态激光放大器:第一个是589 nm的4通放大器，泵浦在532 nm，第二个是660 nm的4通放大器，泵浦在511和578 nm。这些系统分别对应于单色和多色激光导星。

High power modeless lasers for sodium laser guide stars

An increasing number of adaptive optics systems in astronomy uses a sodium Laser Guide Star (LGS). The analysis of the distorsion of the return fluorescence requires high power lasers. We expose here two modeless laser amplifiers, based on a longitudinaly pumped 1 cm-long dye cell: the first one is a 4-pass amplifier at 589 nm pumped at 532 nm and the second one is a 4-pass amplifier at 660 nm pomped at 511 and 578 nm. These systems correspond respectively to the monochromatic and the polychromatic laser guide stars.
