Abstract:

Using the three temperature plasma formulation derived in an earlier paper, the authors have obtained numerical results for argon ion laser discharge parameter as functions of jR the product of current density j and tube radius R for selected values of pR the product of the total filling pressure p and tube radius at a fixed value of Tw the tube wall temperature. The calculated electron temperature is found to be in good agreement with available experimental data. Calculations of the collisional excitation-rate-limited power output per unit length have been made for continuous wave CW argon ion lasers. It is found that the two-step excitation rate is quite adequate in explaining the experimentally observed argon ion laser output power per unit length.
