Selective relaxation of long-lived states of metal atoms in a gas-discharge plasma. Stationary generation of 1P10-0D2 transitions of calcium and strontium

Selective relaxation of metastable states of alkali-earth metals has been effected in a hot-discharge plasma. This has made it possible to realize for the first time stationary lasing on transitions from resonant to metastable levels.
