CFD modeling of static and flowing gas Diode pumped alkali lasers DPALs

An analysis of kinetic and fluid dynamic processes in diode pumped alkali lasers DPALs based on three dimensional computational fluid dynamics 3D CFD models is reported Two schemes for the DPAL gas dynamics are considered: static and flowing gas In the static DPAL the heat transfer from the pump volume is mainly by free convection resulting in considerable heating of the pump volume and large temperature gradients in the gas medium Effects of free convection and
