“…In order to quantitatively analyze the influence of the medium cut angle and doping concentration on the uniformity of the pump light distribution, the relative value of the root mean square error (RMS) can be introduced here to represent the uniformity of the pump light distribution in the medium [2][3][4][5][6][7] Where mn is the m×n equal division of the cross-sectional direction of the inscribed circle at the end face of the medium, Ixy is the pump light intensity at the sampling point, and is the average value of the pump light intensity at all sampling points, The size of the RMS value can quantitatively represent the uniformity of the absorption distribution of the pump light in the medium. The smaller the RMS value, the more uniform the distribution of the pump light.…”

This paper introduces a laser amplifier with a non-uniform concentration of ceramic material as a laser gain medium. This gain medium structure prepared by ceramics is a circular thin-disk with a thickness of about 1mm and the size of the cross-section radius(r) is determined by the signal light to be amplified, the pump light absorption efficiency is generally above 96% and the uniformity of the pump light absorption distribution is a predetermined value, such as 96% or higher. The ceramic gain medium of this non-uniformly doped structure adopts a new way to achieve the uniformity of the gain distribution, this way resolves the contradiction between high absorption efficiency and high uniform gain, it is beneficial to realize high-power, high-efficiency and high-beam quality laser output.
