Excitation of higher lying states in a potassium diode-pumped alkali laser

Dissociative Recombination of K2+ and Rb2+ in Diode-Pumped Alkali Lasers: Potential Energy Curves and Atomic Products

“…In Cs DPAL where hydrocarbon–He mixtures are used as buffers, the influence of the recombination is much weaker. , It proceeds via the sequence including fast conversion of the atomic alkali ions X + to the molecular ions X 2 + ( X = Rb or K) ­( M is either X or He buffer gas atom) and dissociative recombination (DR) of X 2 + where X * is an excited state of atom X , and X ** is another excited or ground state of this atom. As shown in refs , , the DR pathway is dominant, whereas the rate of another three-body recombination pathway involving X + ions is negligibly small. Therefore, the rate of ion–electron recombination in DPAL is determined by the DR rate, which affects the laser power in different DPALs. − It has a particularly strong influence on the operation of K DPAL …”
