We report on a diode-pumped composite ceramic disk laser in this paper. The composite ceramic YAG/Nd:YAG disk consists of 4 mm thick pure YAG and 2 mm thick Nd:YAG with 1.0 at.% doping concentration. The slope efficiency of the composite ceramic disk laser is 36.6% corresponding to the maximum optical-optical efficiency of 29.2%. Furthermore, 340 W average power output was achieved at the absorbed pump power of 1290 W.

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.
