The possibility is considered of detecting metastable copper atoms with the use of Cu–vapor laser radiation at 510.6 and 578.2 nm wavelengths. The fluorescent re-emission channel at 324.7 and 327.4 nm allows the sought information about the concentration of metastable copper atoms to be obtained. Our calculations show that for the layer of copper metastable atoms 10 km thick and number density of 1 atom/cm3 at the altitude of 90 km their detection is possible with the use of a laser with medium performance characteristics both from the ground and from a spacecraft flying at an altitude of 300 km.
