Abstract

The depolarization dynamics in a neodymium glass rod laser amplifier is studied in experiments. A method for determining the temperature distribution and the thermally induced phase distortions by the known transverse depolarization degree distribution is proposed. The experimental results obtained by this method perfectly coincide with the theoretical data even at strong radial inhomogeneity of heat release.
