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

摘要

An active volume scaling in bore and length of a Sr atom laser excited in a nanosecond pulse longitudinal ${rm He{-}SrBr}_{rm{bf 2}}$ 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 ${rm He{-}Ne{-}SrBr}_{rm{bf 2}}$ discharge to find out the optimal temperature regime for achieving of a maximal multiline average output power.
