Dynamics of cataphoresis in the pulse-periodic discharge

摘要

The processes of temporal evolution of metal vapor longitudinal distribution in the pulse-periodic discharge with the cataphoresis delivery of vapor are investigated. In particular, the solution of a non-stationary diffusion equation for the density of metal vapor, averaged for rather large number of pulses, is derived. The axial distributions of metal vapor at different moments of time are calculated. The criteria of uniformity of these distributions are determined. Time intervals are found for homogeneous distribution establishment in typical pulse-periodic MVLs conditions. These time intervals showed to be fairly small, on the order of second. The obtained results demonstrate good perspectives for the use of cataphoresis in pulse-periodic MVLs to form the homogeneous active mediums and, as a consequence, obtain high output characteristics of lasers.
