“…To model experiments by Readle et al [1][2][3] , an initial baseline 5-level XPAL simulation was performed for a configuration including a 2.5 cm diameter, 6 cm long cell heated to 423 K. The laser resonator was comprised of a total reflector and a 50% outcoupler. A 836.7 nm pump beam with a Gaussian temporal profile with a 4.3 ns FWHM and an elliptical spatial profile with a FWHM of 3.5 mm in the X direction and 2.5 mm in the Y direction.…”

“…The exciplex pumped alkali laser (XPAL) system was recently demonstrated [1][2][3][4] in mixtures of Cs vapor, Ar, and ethane, by pumping Cs-Ar atomic collision pairs and subsequent dissociation of diatomic, electronically-excited CsAr molecules (exciplexes or excimers). Because of the addition of atomic collision pairs and exciplex states, modeling of the XPAL system is far more complicated than classic diode pumped alkali laser (DPAL) [5][6][7][8] modeling.…”

The exciplex pumped alkali laser (XPAL) system was recently demonstrated in mixtures of Cs vapor, Ar, and ethane, by pumping Cs-Ar atomic collision pairs and subsequent dissociation of diatomic, electronically-excited CsAr molecules (exciplexes or excimers). Because of the addition of atomic collision pairs and exciplex states, modeling of the XPAL system is far more complicated than classic diode pumped alkali laser (DPAL) modeling. In this paper we discuss BLAZE-V multi-dimensional modeling of this new laser system and compare with experiments.

“…In the first year, we studied exciplex pumped alkali laser (XPAL) which was first demonstrated by the group of University of Illinois and CU Aerospace [5] [6]. We succeeded in oscillation for both 4-level and 5-level principles, and measured some fundamental properties of the active media [7].…”

Activities on diode pumped alkali laser (DPAL) in Japan is reviewed. We have started alkali laser works in 2011, and currently, we are the only players in Japan. Our interests are application oriented, and it is not only defense but also industrial. DPAL is a good candidate as a source of remote laser machining, thanks to its scalability and extremely good beam quality. We are studying on scientific and engineering problems of Cs DPAL with a small-scale apparatus. A commercial diode laser with volume Bragg grating outcoupler is used to pump the gain cell longitudinally. A 6.5 W continuous-wave output with optical to optical efficiency of 56% (based on the absorbed power) has been achieved. Numerical simulation codes are developed to understand the physics of DPAL and to help future developments.

“…Furthermore, the blue satellites of the alkali D 2 lines provide a pathway for optically pumping atomic alkali lasers on the principal series transitions with broad line width semiconductor [1]. In fact, alkali vapor lasers pumped by diode lasers are currently being investigated extensively in order to construct high powered lasers with high beam quality.…”

The potential energy curves of the ground state and many excited states of the RbAr van der Waals complex have been determined using [Rb + ] and [e-Ar] pseudopotentials with the inclusion of core polarization operators on both atoms. This has reduced the number of active electrons of the RbAr system to only one valence electron, permitting the use of large basis sets for both the Rb and Ar atoms. Potential energy curves of the ground state and many excited states have been calculated at the SCF level. The core-core interactions for Rb + Ar are included using the accurate CCSD potential of Hickling et al [Hickling, H.;Viehland, L.;Shepherd, D.; Soldan, P.;Lee, E.; Wright, T. Phys. Chem. Chem. Phys. 2004, 6, 4233]. Spectroscopic constants for the ground and excited states of RbAr are derived and compared with the available theoretical and experimental results. Furthermore, we have predicted the X 2 6 + ---A 2 1/2 , X 2 6 + ---A 3/2 and X 2 6 + --B 2 6 1/2 + absorption spectra.
