Theoretical studies of the feasibility of supersonic DPALs Conference Paper uri icon

abstract

  • 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 …
