We have observed a large variation with laser polarization in the amount of laser light resonantly backscattered from the Earth's mesospheric sodium layer located at a 90-km altitude. This variation is evidence of optical pumping of mesospheric sodium atoms.
我们观测到，从位于90公里高空的地球中层钠层共振反向散射的激光量会随激光偏振发生很大变化。这种变化是中层钠原子光泵浦的证据。
