Calculations of three-dimensional distributions of current density, electric field, and power deposition in externally sustained electrical discharges. [For calculating performance of CO/sub 2/ laser]

PDF Version Also Available for Download.

Description

In the design of larger and larger CO/sub 2/ laser amplifiers, the problem of attaining the ideal uniform discharge in these large discharge volumes becomes increasingly difficult and expensive to solve. The practical solution is a compromise between uniformity and other design considerations. In order to judge the adequacy of each compromise, a method of predicting the distribution of current density and electric field throughout the discharge volume is needed. When these electrical distributions are known, population inversions can be calculated and the amplifier performance evaluated. This report describes a method of calculating the three-dimensional distributions of electric field and ... continued below

When these electrical distributions are known, population inversions can be calculated and the amplifier performance evaluated. This report describes a method of calculating the three-dimensional distributions of electric field and current density for externally sustained discharges. Two-dimensional calculations have been reported previously.
