Advanced Diode Pumped Alkali Lasers: Theoretical Investigations and Modeling,
Abstract
Our objectives are to theoretically study basic processes and develop new concepts of DPALs, in particular of flowing-gas ones. Reliable and predictive 3D CFD models, based on updated measurements, will be developed and applied for choosing parameters for designing subsonic and as-yet unexplored supersonic DPALs. We will first concentrate on continued development and fine tuning of 2D and 3D CFD models of flowing-gas DPALs, including the previously unexplored supersonic flows in these systems. The elaborate codes for the models will be tested using the available kinetic data , by checking if they result in a reasonable agreement with available experimental results of DPALs operation and with those of our previously developed semi-analytical models. We will then continuously update the kinetic data as provided by laboratories currently investigating these processes (M. Heaven at Emory University (EU), R. J. Knize at U.S. Air Force Academy (USAFA) and others). The interaction with these labs will permit identification of problems with both the models and the mechanism, and also facilitate the discovery of alternative kinetic schemes.
