NUMERICAL AND EXPERIMENTAL-ANALYSIS OF COPPER-VAPOR LASER DISCHARGE

The differential equations describing discharge circuitry are presente d. The thyratron resistance with a switching time coefficient tau(s) i s investigated. The plasma conductivity used in these differential equ ations is estimated using the available data on plasma parameters. The discharge current profile of numerical simulation is found to be in c lose agreement with the experimental data. In this way, the factors wh ich affect the short rise time to increase lasing ability in the CVL ( copper-vapor laser) are studied. As a calculation result, the inductan ce of the laser head is subordinate to the thyratron circuit inductanc e in terms of the effect on the discharge current rise time. Very good agreement exists between the calculated and measured results. (C) 199 8 John Wiley & Sons, Inc.
