Three-dimensional computational fluid dynamics (3D CFD) modeling of subsonic (Mach number M ~ 0.2) and transonic (M ~ 0.9) diode pumped alkali lasers (DPALs), taking into account fluid dynamics and kinetic processes in the lasing medium is reported. The performance of these lasers is compared with that of supersonic (M ~ 2.7 for Cs and M ~ 2.4 for K) DPALs. The motivation for this study stems from the fact that subsonic and transonic DPALs require much simpler hardware than supersonic ones where supersonic nozzle, diffuser and high power mechanical pump (due to a drop in the gas total pressure in the nozzle) are required for continuous closed cycle operation. For Cs DPALs with 5 x 5 cm² flow cross section pumped by large cross section (5 x 2 cm²) beam the maximum achievable power of supersonic devices is higher than that of the transonic and subsonic devices by only ~ 3% and ~ 10%, respectively. Thus in this case the supersonic operation mode has no substantial advantage over the transonic one. The main processes limiting the power of Cs supersonic DPALs are saturation of the D2 transition and large ~ 60% losses of alkali atoms due to ionization, whereas the influence of gas heating is negligible. For K transonic DPALs both the gas heating and ionization effects are shown to be unimportant. The maximum values of the power are higher than those in Cs transonic laser by ~ 11%. The power achieved in the supersonic and transonic K DPAL is higher than for the subsonic version, with the same resonator and K density at the inlet, by ~ 84% and ~ 27%, respectively, showing a considerable advantaged of the supersonic device over the transonic one. For pumping by rectangular beams of the same (5 x 2 cm²) cross section, comparison between end-pumping - where the laser beam and pump beam both propagate at along the same axis, and transverse-pumping - where they propagate perpendicularly to each other, shows that the output power and optical-to-optical efficiency are not affected by the pump geometry. However, the output laser beam in the case of end-pumped DPALs has a homogeneous spatial intensity distribution in the beam cross section, whereas for transverse-pumped DPALs the intensity varies significantly along the pumping axis (perpendicular to the resonator optical axis) and hence is strongly inhomogeneous in the laser beam cross section. Thus, higher brightness and better beam quality in the far field is achieved for the end-pumping geometry. Optimization of the resonator geometry for minimal gas temperature rise and minimal intra-resonator intensity (corresponds to a low ionization rate) is also reported.

Results of recent semi-analytical and three dimensional computational fluid dynamics (3D CFD) modeling of supersonic diode pumped alkali lasers (DPALs), as well as summary of work in progress, are reported. DPALs have been extensively studied in the past few years and static and flowing-gas devices have been investigated. Modeling of these devices has been conducted as well and fluid dynamics and kinetic processes have been taken into account, but until recently only flowing-gas DPALs with subsonic velocity of the gas were considered. Following our previous work on supersonic DPALs we further explore in the present study the feasibility of operating DPALs with supersonic expansion of the gaseous laser mixture, consisting of alkali atoms, He atoms and (frequently) hydrocarbon molecules. The motivation for this exploration stems from the possibility of fast and efficient cooling of the mixture by the supersonic expansion. In a recent paper (S. Rosenwaks et al, Proc. SPIE 8962, 896209 (2014)) we have reported on semi-analytical modeling for a supersonic Cs DPAL with parameters similar to those of the 1-kW flowing-gas subsonic Cs DPAL (A.V. Bogachev et al, Quantum Electron. 42, 95 (2012)); the maximum power, P_lase, for the former was found to be higher than for the latter by 25%. Optimization of the He/CH₄ buffer gas composition and flow parameters using 3D CFD modeling shows that for Bogachev et al resonator parameters, extremely high lasing power and optical-to-optical efficiency, 33 kW and 82%, respectively, are achievable in the Cs supersonic device. Comparison between the semi-analytical and the 3D CFD models for Cs shows that the latter predicts much higher maximum achievable laser power than the former. For a supersonic K DPAL the semi-analytical model predicts P_lase = 43 kW, 70% higher than for subsonic with the same resonator and K density at the inlet, the maximum optical-to-optical efficiency being 82%. The paper also includes estimates for closed cycle supersonic systems.
