Calculation of the Output Power of the Argon-Ion Laser Superimposed by a Magnetic Field

The generalized positive-column theory has been applied to calculate the plasma parameters in the argon-ion laser discharge on which an axial magnetic field is superimposed. Then, population densities of the excited levels of argon ions and the laser output power have been obtained on the basis of the collisional-radiative model. The results explain quantitatively the experimental relations between the output power and the magnetic field. Furthermore, in order to examine the validity of the present calculation, the calculated electron temperature and density have been compared quantitatively with the semi-experimental values derived from the spectral-line intensity data on ArI and ArII.
