2-D Numerical Modeling of Gas Temperature in Large-Volume Sr Laser Excited in Nanosecond Pulsed Longitudinal ${\rm He{-}SrBr}_{2}$ Discharge

An active volume scaling in bore and length of a Sr atom laser excited in a nanosecond pulse longitudinal He-SrBr
₂
discharge is carried out. Considering axial symmetry and uniform power input, 2-D model (r, z) is developed by numerical methods for determination of gas temperature in nanosecond pulsed longitudinal He-Ne-SrBr
₂
discharge to find out the optimal temperature regime for achieving of a maximal multiline average output power.
