Abstract
Lasing on the 62P1/2→62S1/2(D1) resonance transition of atomic Cs at 894.3 nm has been demonstrated in mixtures of Ar, ethane, and Cs vapor by the photoexcitation of ground state Cs-Ar collision pairs and subsequent dissociation of diatomic, electronically-excited CsAr molecules (exciplexes or excimers). The blue satellites of the alkali D2 lines provide a pathway for optically pumping atomic alkali lasers on the principal series (resonance) transitions with broad linewidth (>2 nm) semiconductor diode lasers. In this paper we discuss different variations of this new laser system and the experiments of the initial demonstration.
