S.AbstractIn the region near 1μm, we have found laser action in a quantum transition between highly excited states of Fe II, with its higher levels being optically pumped by the intense H Lyα radiation (1215 Å) formed in the ionized HII region of a gas condensation (blob B) in the close vicinity of the central star in η Carinae. © 2002 MAIK “Nauka / Interperiodica”.SubjectsEARLY stars; QUANTUM theory; LASERSPublicationJETP Letters, 2002, Vol 75, Issue 10, p495ISSN0021-3640Publication typeArticleDOI10.1134/1.1497875
