Over the last decade new advanced gas lasers have emerged as possible candidates for high power laser systems that may supplant more conventional chemical and gas laser systems. Among these are the electric oxygen-iodine laser (ElectricOIL), the diode pumped alkali laser (DPAL), the exciplex pumped alkali laser (XPAL), and the optically pumped metastable rare gas laser. In this paper we will primarily focus on the ElectricOIL and XPAL systems, and discuss some of the recent experiments and modeling of these systems.

“…The absorption occurs on the X B molecular transition, and the B-state promptly dissociates directly into the 2 P 3/2 state, producing inversion on the D 2 transition. 12 Inversion can also be created on the D 1 transition by using C 2 H 6 to promote the spin-orbit transfer, as in DPAL. XPAL requires elevated temperature to increase the alkali atom concentration, and elevated rare gas pressure to promote the exciplex formation.…”

In this paper we present experimental results on several features of optically excited alkali atoms. We describe small signal gain measurements including spatially-resolved gain in atomic Cs. We discuss observations of numerous near-to mid-IR emissions from states that are higher in energy than the pump beam photons. Finally we outline a measurement scheme to determine the threshold pump intensities for two types of optically excited alkali lasers.

“…Interactions of alkali metal atoms with rare gas atoms are of great importance in several areas of physics and chemistry. These interactions have been investigated experimentally − and theoretically − for many years and for many systems. In fact, they are considered as model systems for van der Waals molecules.…”

“…Theoretically, there are several calculations − of the interactions between the alkali atoms with noble gas atoms. The M( 2 S) + Rg pairs (M = alkali; Rg = rare gas) were investigated by Baylis using pseudopotential method and spin–orbit coupling.…”

Using an ab initio approach based on pseudopotential technique, pair potential approach, core polarization potentials, and large Gaussian basis sets, we investigate interaction of heavy alkali−krypton diatomic M−Kr (M = Rb, Cs, and Fr) van der Waals dimers. In this context, the core−core interactions for M + − Kr (M = Rb, Cs, and Fr) are calculated at coupled-cluster single and double excitation (CCSD) level and included in the total potential energy. Therefore, the potential energy curves are performed for 14 electronic states: eight of 2 Σ + symmetry, four of 2 Π symmetry, and two of 2 Δ symmetry. Furthermore, for each M−Kr dimer, the spin−orbit coupling has been considered for the B 2 Σ + , A 2 Π, 3 2 Σ + , 2 2 Π, 5 2 Σ + , 3 2 Π, and 1 2 Δ states. In addition, the transition dipole moment has been determined, including the spin−orbit effect using the rotational matrix issued from the spin−orbit potential energy calculations.
