Abstract
Spectral
analysis of laser radiation emitted by diatomic molecules and simple
theoretical models have allowed us to study population-inversion
mechanisms in the u.v. and i.r. for N2 and visible CO
molecular lasers. The technique is readily applicable to other diatomic
molecules. Observations of Λ -doubling in N2 u.v. laser
emission and analysis of rotational structure in i.r. laser emission for
the same molecule are used to determine the main features of electronic
excitation and different channels for population of the laser levels
involved. For the visible molecular CO laser, a fit of the rotational
intensity distribution of the emitted visible bands was used to
determine enhancement mechanisms by which population inversion is
achieved in some Q-branch transitions.
