Paper Abstract

The theoretical solution to the absorbed pump light inside a laser medium is presented. It is shown that the pump light absorbed with respect to the transport distance is not simply an exponential function. When the pump intensities go high enough, their relation becomes a nonexponential function. These theoretical results have been applied to YAG:Nd, and the regularity of pump light intensity variation inside a laser medium is indicated. We experimented with YAG:Nd, and the experimental result is in agreement with the theoretical result.
